Q & A
What is the role of decomposers in the ecosystem?
-Decomposers, such as bacteria, fungi, and earthworms, break down dead organic matter, returning important nutrients back into the soil for plants to use.
How are all living things connected in the food chain?
-All living things are connected through a food web, where plants serve as the primary producers, and animals are consumers that eat plants or other animals.
What is photosynthesis and why is it important for life on Earth?
-Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose (sugar) and oxygen. It's important because it provides food for plants and oxygen for animals, including humans.
Where does most of the Earth's photosynthesis occur?
-A significant amount of photosynthesis takes place in the ocean, particularly by microscopic plants like algae, which thrive in the abundant sunlight and stable environment.
How does a food pyramid illustrate the flow of energy in an ecosystem?
-A food pyramid shows the flow of energy from plants at the bottom to fewer and fewer animals at the top. It demonstrates that as you move up the pyramid, there is less energy available, which is why there are fewer large animals.
Why is it said that all animals, including humans, depend on plants?
-All animals, including humans, depend on plants because they produce oxygen through photosynthesis, which is essential for animal respiration. Without plants, the oxygen levels would not be sustainable for animal life.
What is the significance of the food web in an urban environment like New York City?
-Even in urban environments, the food web is significant as it connects the various forms of life, including humans, animals, and microorganisms. It illustrates the interdependence of all living things, regardless of the environment.
How can one grow plants without soil?
-Plants can be grown without soil using techniques such as hydroponics, where plants are grown in a nutrient-rich water solution, or aeroponics, where the roots are misted with the nutrients they need.
What is the role of sunlight in the growth of plants?
-Sunlight is essential for photosynthesis, the process by which plants convert sunlight into energy to fuel their growth. Without sunlight, plants cannot produce the food they need to grow.
Why is it important to understand the source of our food?
-Understanding the source of our food helps us appreciate the complexity of ecosystems and the interconnectedness of life. It also encourages us to make more informed choices about what we eat and how our food is produced.
How does the concept of a 'food web' differ from a 'food chain'?
-A food chain is a linear sequence of organisms where each is eaten by the next one up the chain. A food web, on the other hand, is a more complex network that shows the interconnectedness of multiple food chains, illustrating the variety of feeding relationships in an ecosystem.

Transcripts
here's your wedding meal sir oh boy
Thanks
and don't forget your decomposers couple
worms oh boy
plants and animals big opposes ooh ooh
dad is gonna kill you that's where the
food was all about yeah food whoops
that's what today's show is all about
[Music]
top you buy plant plants our food you
know that all living things depend on
plants
that's right if there were no plant
there'd be no us see you can't play it
or you are a plant or you eat things
that you claim everything that eats
everything that's alive is connected and
we call these connections to prune when
you're part of the to pal to me we me
it's probably something eating at you
right now you no matter what food we're
talking about them we can always tie it
back into plant and the post for example
I was going to enjoy this chicken simile
here on the outside we have a piece of
bread so let me tie the chicken sandwich
to the food web by attaching it to fleet
and wheat by the way is a plant now then
which also has some lettuce and lettuce
is over here now it's at a meat of the
matter the chicken
you know chickens boy that's right a
corn is a plant
now also on my sandwich some Tomatoes
everything it's really important you
look excited yeah it's all tied to plant
you know I'm kind of tangled up in here
and part of food web
[Music]
[Music]
where does food come from a shopping
center where's the shopping center get
it I don't know does it come from farms
yeah I guess you ever been on a farm
nope you ever see the call sure on
television
[Music]
hey Alfonso what are you doing well I
just you know what's growing you know
the crops the flowers usual it's
beautiful man not those bill these look
Oh the decomposers
yeah bacteria fungi earthworms all the
things that he did stuff like you just
look at all those decomposing important
nutrients back into the soil from plant
to use is important right bill because
we all depend upon land this is a gun
hamburger it means I came from a cow now
what do you think that Kali Kali grass
addresses yeah a plant water reaching
even vegetable then you want happy my
vegetables if your mother says you do
you do well yes
I mean you colonists because all living
things depend on plants and you however
living say I am
I'm gonna come from here now plants make
good food and good oxygen it's a good
thing they're everywhere on land hey
what do you think I know I think he's
saying most of the plants on earth live
in the ocean a lot of photosynthesis
takes place down here a lot of the
plants are microscopic like algae
there's plenty of sunlight and no need
to worry about win or getting uprooted
the ocean for cryin out loud
everything's recognized on the counts
megalopolis it's possible to live a
lifetime without seeing food producing
animal or even growing crops megalopolis
has exchanged the farms at the
surrounding countryside for the farms of
and never before has there been such
great variety in the selection of foods
available so where does our food come
from anyway you might think it comes
from a grocery store so what do you do
you go to the grocery store you hunt for
your food you gather it up then you buy
it but if we were real hunter-gather
scavengers like our ancestors we grind
our own weight grow it on vegetable
squeeze oranges to make orange juice and
because time tuna here to take a longer
than I thought it would
as long as I understand it all living
things depends on plants I've been told
that they call this road where you can
do that plants need light to grow take
you on this so each of the glass of
water you might have to stick toothpicks
on the sides together stay put wearing
with my Windham it'll get my design the
other is that close in a week
check them out this on you miss Brody
please turn green the plum Canyon isn't
getting your distinction so it's not as
green what sounds fun and you can't grow
but why not when you keeps getting
bigger and bigger
semi semi it about turn maybe no branch
milkman yes is no food no sweat whoa
when you're feeding a family it's
important always help you sit today
that's why we could catalyze please hey
now is my room now now there's enough
time for everyone thanks to the side
where Jim Eden is Phil Levin
plants get the energy they need to live
from the Sun plants make their food
using sunlight carbon dioxide and water
the process is called photosynthesis
that means making from light see
basically plants make sugar like this
grape hmm
nicely sugar is made from carbon
hydrogen and oxygen that's what's in
sugar see animals breathe out carbon
dioxide animals like you and me it's the
same gas that's been that soda water
anyway here's the deal all animals
including you and me need oxygen to
breathe see animals breathe in oxygen
and breathe out carbon dioxide plants
breathe in carbon dioxide and breathe
out oxygen so even if you go I'm never
gonna eat my broccoli again all animals
that includes you pal me me me
need plants because we need oxygen to
breathe if plants weren't out there
making their own food from sunlight
carbon dioxide and water we animals just
couldn't be here thank you for joining
me on
consider the fall there's a lot of foods
that basically like this most of the
time you clean your plate and don't have
quite even if it leaves a bad taste in
your mouth
my name is Luna Luna van Dijk it's a
Dutch name that means photosynthesis I'm
a detective
you order pizza no I know I can't Oh
where'd it come right here
[Music]
okay
Hey
and
and I got your answer your pizza can't
complain
but Reyes from local control presenters
and shown now I sent trans listen wise
guy
everything on it from the cheese on top
to the crust on the bottom can complain
there's no easy way out of this one oh
yeah well this one came from pizza quick
oh and if you want to eat your way out
of this one you're gonna have to baby
7:59 paying anything I didn't order
about a patient I gotta pay identity we
wanted to
[Music]
[Music]
so Dave where are we we're in the
creative house tool and greenhouse at
Epcot Center agricultural showcase I'm
aware apostle is so my main function
here if you just wrote a plan so what do
you showcases showcasing - fine
technique the growing plants using
method other than soil some of them are
actually banging engineer far back
second number I like plan more like a
plan suspenseful because you're going to
need it light up - you can grow your own
seeds by planting them in different soil
get some earthy and put a few grain
seeds in a glass of sherry dirt or new
soda and one right so which seeds you
think about first well fine try it try
this at home and write and tell us what
happened
we'll send you a cool science kit
writing science games post office box 36
26 see I'm Washington ninety one two or
three six two six offer valid well I
plan Richie you are not leaving this
table until you eat all of your
vegetables that's not fair
- by his vegetables
[Music]
[Music]
you know you wouldn't think that there's
a lot of aquatic life in the food webs
in New York City so here we are standing
at the northern tip of the island the
Big Apple and we have lots of things to
see and discover let's go sign because
even though we have all this junk
laughter with the animals and all the
microorganisms are you know without
mother nature like nothing else in
survived because we're at the bottom of
the Machine under the highest things
which we are to survive either the food
web is really based on a food pyramid
yeah with lots of plants at the bottom
and just a few big animals like you and
me at the top let's say we've got a
plant let's say we've got an apple tree
well the apple tree gets the energy that
it needs to live from the Sun and it
makes so that ten animals forms along
with each and every animal we're giving
the energy that it needs to live from
the energy that was in the app from the
plant and let's say that the animal that
AG Apple gets eaten by a bigger animal
of a bigger animal is getting the energy
that it needs to live from the energy
that was in the small room it's getting
energy that it needs to live from the
plants just indirectly so you can see
that as we go farther and farther up the
food pyramid there's less and less
energy from plants to go around that's
why they've got to be a lot more plants
than there are animals the food pyramid
is got to be a lot lighter at the bottom
than it is at the top
[Music]
I can't I must go brand I'm a little
ticked off sometimes I get mad but I'm
always being your friend hi kids
today's words is food web I know it
looks like two words but it's one idea
here's a little poem you probably
already know there was an old lady who
swallowed a spider that wiggled and
jiggled and tickled inside early why
should it I don't go friends because
that's the way the song goes mr. raccoon
understand what no you wouldn't swallow
a spider at the grocery swallowed the
spider to catch the fly I don't know why
she's multiplying she'll die it's just a
song about a woman not living in a real
food web mr. raccoon it's not real now
the food web is real mr. raccoon man
it's swallowing the spider to catch the
fly that doesn't work so well get it now
doesn't make any sense to me no I know
something might help Oh how's that we
didn't anything no let me out no I'll
try it again
oh no wait wait you know what it's
starting to come in now yeah I thought
yeah yeah real clear okay a public
service announcement for science you
know then everyone's a professional
scientist but today what you do sign
it's an idea that I think is best
expressed in a song oh boy
in the past in the future in this
councils and the future
we began through the car that makes it
run there's a discipline that's true
manifested through injury it's all
science and it's part of everyone okay
then I just imagine the food web out
here okay I mean I mean there's some
people over there and they're going to
grocery shopping at a store and then
there's some trucks bringing some
groceries to the store and then over
there are some grain elevators the grain
light came from some feel really sorry
insects in the field eating some of that
grain on this road and seating those in
of course all that comes or that does
are plant the wheat has plants that's
good light from the Sun already shown
over here making the plants grow and
then we animals kill me me Oh mommy we
all need the plants do you pick so
imagine the food web going over the edge
into the water when I serve fish there's
fish by the truckload by the boatload by
the ocean mode out there and then
there's a lot of photosynthesis on on
there right okay look past that there's
mountain there's a whole nother
ecosystem over there's a whole bunch of
other stuff going on like
[Music]
we'll take a look at my place there's a
side to the table food while I'm sitting
over and it looks like a milk like I
mean I got pasta okay I got chicken
enables about a feedback I got mono
question I got tacos I'm a fish we're
not even seems like a vegetable dish but
the truth of the matter of the do
scintillating is the all these basic the
software vegetation
[Music]
have to eat and we will need weeks yeah
we need half of the things that we close
to them these days and these bees they
get fallen from the package and abuse
and the trees but maybe not your
happiest think what the plant needs they
got a couple of second you know they got
a piece well a plant needs water and a
plant needs carbon dioxide and oxygen
Oh glorious food oh hi
oh that's our show thanks for watching
just use me I got some serious plans to
depend on this is I mean you're not
going anywhere so give this those
vegetables okay all we have are some
okay - please stop doing that
produced in association with the
National dementia senility is voice
again taken to the tune to the crew you
landed like you know what you mean
though that we make implemented
[Music]
[Applause]
