Q & A
What is the significance of forests as terrestrial ecosystems?
-Forests are significant terrestrial ecosystems due to their beauty, economic value, and the abundance of life they support, making them an important part of our culture.
Why is soil important in a forest ecosystem?
-Soil is crucial in a forest ecosystem as it is where most plants get their food and water, many animals make their homes, and important nutrients are recycled.
How long does it take for an inch of soil to form in a forest?
-It takes up to a thousand years for only one inch of soil to form in a forest.
What is the role of decomposers in a forest ecosystem?
-Decomposers, such as fungi and earthworms, consume dead plants and animals and help turn them into soil, enabling the recycling of nutrients.
What type of forest is most common in North Carolina and throughout the U.S.?
-Deciduous forests, which are made up of tall trees that usually lose their leaves in the winter, are the most common type in North Carolina and throughout the U.S.
What are producers in a forest ecosystem, and why are they important?
-Producers are organisms that turn sunlight, water, and carbon dioxide into products like fruits, leaves, and bark, providing energy for consumers. They are important because they form the base of the ecosystem.
How do trees provide habitats and food for other organisms in a forest?
-Trees provide habitats and food for other organisms by offering shelter, hunting grounds, and when they drop leaves, branches, or die and fall over, they create habitats and food for a community of invertebrates.
What are primary consumers in a forest ecosystem, and why are they important?
-Primary consumers are animals that feed directly on the trees, such as insects, small birds, and mammals. They are important as they are the first to take the energy created by producers and use it for their own growth.
What is the role of secondary consumers in a forest ecosystem?
-Secondary consumers, which may include carnivorous or omnivorous animals, help keep populations of their prey in check and provide energy for the top predators in the forest ecosystem.
Why are apex predators important in a forest ecosystem?
-Apex predators, such as the red-shouldered hawk, are important because they help control populations of lower consumers, ensuring a balance in the ecosystem and preventing any one species from overpopulating.
What benefits do forests provide to human beings?
-Forests provide numerous benefits to humans, including timber harvest revenue, offering beautiful landscapes for relaxation and enjoyment, and helping to filter toxins from the air and water.

magical peaceful mysterious forests have
intrigued humans for thousands of years
and are some of the most famous
terrestrial ecosystems on the planet
their beauty economic value in the
abundance of life that they contained
has made these habitats an important
part of our culture how much do you
really know about these famous natural
areas
hey there explorers and welcome to the
forest ecosystem today we're gonna be
taking a look at some of the amazing
plants and animals that call this place
their home in exploring the interactions
that MIT all-fours two organisms
together to start our adventure we need
to look down all life in the forest
starts in the soil this is where most
plants get their food and water
many animals make their homes and
important nutrients are recycled do you
know that it takes up to a thousand
years for only one inch of soil to form
that's because swittel is actually made
up of thousands of teeny portals of
organic matter in a few minerals organic
matter is just teeny pieces of dead
plants and animals that have been broken
down over time by a process known as
decomposition this process wouldn't be
possible without the help of special
organisms known as decomposers
decomposers are special organisms such
as fungi and earthworms that consume
dead plants and animals and help turn
them into soil usually the process of
decomposition is started by scavengers
such as vultures and then continued by
these decomposers without them it would
be much harder for nutrients to make
their way back into living plants such
as the trees that dominate the forest
ecosystem
it's that large amount of organic matter
that gives for soil its dark color high
nutrient content and makes trees be able
to grow so tall right now we are in
deciduous forests made up of tall trees
that usually lose their leaves in the
winter while there are many other forest
types this is the most common forest
found here in North Carolina
in throughout the u.s. trees are the
most abundant type of producer in this
ecosystem producers are organisms that
turn sunlight water and carbon dioxide
into products like fruits leaves in bark
that provide energy for consumers that
can't make energy on their own this
means that producers are the base on
which almost all ecosystems are built
especially here in the forest not only
do trees provide food they also create
numerous homes for all kinds of
different forest dwelling animals birds
take shelter in the thick branches
snakes hunt rodents on the forest floor
deer rely on the thick vegetation to
hide from predators when trees drop
their leaves branches or die and fall
over they create habitats and food for
an entire community of invertebrates
that rely on decomposing trees for their
food and shelter those arthropods that
feed directly on the trees are an
example of primary consumers because
they are the very first animals that
take the energy created by the producers
and use it for their own growth in a
forest ecosystem primary consumers
include many insects small birds and
mammals as the second step up from
producers these organisms are important
prey sources for almost all higher-level
consumers in the forest insects in
particular are consumed by a huge
variety of birds reptiles and Finian's
and small mammals since so many
different animals like to eat insects
it's a good thing that there's plenty of
them around hoping over a single down
like this one can reveal a community of
hundreds if not thousands of the little
guys and gals going about their daily
business without these little protein
snacks they are be much less food for
secondary consumers secondary consumers
are organisms that usually rely
partially on eating other consumers and
apart on eating producers to gain the
energy that they need to live snakes are
an example of carnivorous secondary
consumers that only eat other animals
and raccoons are a good example of
omnivorous secondary consumers that may
eat other animals or plant parts there
are many many different species of
secondary consumers because of how much
energy is available to these animals
from both primary consumers and the
producers making up the middle layer of
the ecosystem secondary consumers help
keep populations of their prey items in
check while also providing energy for
the top dogs in the forest ecosystem the
apex predators not all forest ecosystems
have apex predators but even small
forest fragments usually contain enough
prey for at least one or two of these
toc level consumers also known as
tertiary consumers organisms at this
level of the ecosystem almost only
consume other consumers and require lots
of energy to remain healthy and
reproduce they have almost no natural
predators and are often among the rarest
species in natural systems one example
of a top predator is this gorgeous red
shouldered Hawk training on mammals
reptiles and even smaller birds red
shouldered Hawks keep a huge variety of
prey atoms in check ensuring that none
of their populations become too large
and take too much energy from other
organisms while nothing else in the
forest relies on the hawk as a food
source it will still provide energy for
other organisms when it dies and
decomposes to become highly nutritious
soil to fuel plant growth without a top
predators like red-shouldered Hawks
populations of lower
consumers could grow out of control and
overrun the rest of the ecosystem
healthy forests provide a number of
benefits to human beings timber harvest
provides over two hundred billion
dollars of revenue to the US alone
forested landscapes are beautiful places
to relax and enjoy nature and trees take
in and filter out toxins from the air we
breathe in the water we drink without
forests our planet will be much hotter
much drier and have much less
biodiversity thanks so much for joining
me in today's adventure and learning a
little bit more about forest ecosystems
and the organisms that make them up on
our next adventure we'll be checking out
the second type of terrestrial ecosystem
the grassland until then stay curious
and keep adventuring everywhere this has
been Zeno of the wild report signing up
