Without sunlight, plants cannot grow, and animals cannot get food, leading to the eventual death of all living things. The video highlights the significance of sunlight in maintaining life, showing how life on Earth would be impossible without it.
💧 Significance of Water for Living Beings
Water is essential for all living things. Animals cannot survive without drinking water, and plants need water to make their food. The human body is about 70% water, emphasizing its importance. Without water, humans can only survive for a few days. The video underscores the critical role of water in sustaining life.
🌬️ Necessity of Air for Life
Air is vital for the survival of living organisms. Humans can hold their breath for a limited time before needing to breathe in air. Plants also require air for respiration and photosynthesis. The video explains how plants use sunlight, water, and air to make their food and highlights the interdependence of living things on these elements.
🌱 Importance of Soil for Plants and Animals
Soil provides support and nutrients to plants, helping them grow. It also offers a habitat for many animals, like ants and rabbits, which live underground. The video discusses how soil supports plant life and provides homes for various animals, making it an indispensable factor for sustaining life.
📝 Recap and Assessment of Learned Concepts
The video concludes with a summary and assessment of the key points covered. It reviews the factors necessary for life: temperature, light, water, air, and soil. Viewers are asked questions to reinforce their understanding, such as identifying organisms that make their own food (plants) and recognizing the best temperature conditions for life (moderate temperatures). The sun is highlighted as the primary source of energy for all living things on Earth.

assalamualaikum and welcome back to my
youtube channel
today we are going to learn about earth
as a living planet and the topic is
factors required to sustain life on
earth so are you ready
let's start by the end of the lesson
you should be able to identify five
factors that support
life on earth
determine what kind of temperature
conditions do living organisms need to
survive
[Music]
and describe how light
water air and soil
play their part in sustaining the life
on earth
[Music]
factors required to sustain life on
earth
are sunlight water
air temperature and soil
these are the basic needs of a living
organism
living things cannot survive if
any of these factor is not available
life is not possible without these
factors
can you rename these factors with me
[Music]
these factors are number one temperature
what is the second one yes
it's light third one is
water fourth air
and the fifth one is soil
[Music]
how are you feeling today are you
feeling hot
or are you feeling cold
temperature of the surroundings make you
feel
cold or hot
all living things need to live in a
particular temperature
if the temperature is too cold as the
case here
we cannot survive and
if the temperature is too hot again
the life is too high to live on
living things cannot survive if the
temperature
is too high or too low
[Music]
so the temperature on the earth is just
right
for the life to happen here you see
the distance between the sun and the
earth
is just right if it would be
to the left the temperature conditions
would be too
hot for life to live on
and if it would be on the right it would
be
too cold for life to survive
the distance of earth from the sun is
the most
appropriate to sustain life on earth
another factor important for life is
light
during day time there is light where
does this light come from
you can see this is a picture of
day the light you can see
is coming from the sun
the sunlight comes from the sun
the sun is the main source of light
and heat on the earth
so where does this light come from
the light we see on the earth come from
the sun what would
happen if there is no sun
or earth will look like this
other than this see this is a living
planet
with greenery and water none of this
would be there
if there is no sun if there is no sun
there would be no light and no heat
plants would not be able to grow and
animals would not be able to get food
eventually all the living things would
die
water is another important factor
of life why do living things
need water animals cannot survive
without drinking water and plants
they need water to make their food
without water plants and animals
cannot survive
water in human body do you know how much
of our body is made of water
about 70 percent of our body is made of
water
that is how important water is for us
without water we will not be able to
live
for more than three days all living
things
need air let's see how long
you can hold your breath
maybe for 5 seconds
or 10 seconds
well maybe for 30 seconds
eventually you need to breath
air in you have to breathe in
because all living things need air
[Music]
why do plants need air
plants also breathe in and breathe out
like us plants need air
to make their food plants need sunlight
and water along with air to make their
own food
soil you saw in the previous picture
the plant was standing where does
the plant get its support to stand on
that support is provided by the soil
soil provides support to plants
they take nutrients from soil
as well as the support so the plant
when it is very small start getting its
roots out
as the roots go into the soil
the plant keep growing
can you name some animals that
live in the soil
ants and rabbits are some of the animals
that live in the soil
[Music]
that is how they made their home in the
soil
and they live underground
so the soil not only support
the plants it also provide
homes to many of the animals
so now we will assess what we have
learned
so far so the first question is
which of the following group of living
things
can make their own food is it the plants
or is it the animals
and the correct answer is plants are the
living things
that make their own food
[Music]
so the next question is which of the
following places
are the most suitable for living things
is it the extremely cold places
like this one or places with moderate
temperature
like this or the extremely hot places
like this one here
and the correct answer is
places with the moderate temperature are
the most suitable places for
living things another question is
which of the following is the biggest
source of
energy for us
is it the sun
or is it the moon and the correct answer
is
sun sun is the biggest source of
energy that is heat and light
for all the living things on the earth
shall summarize what we have learned so
far
we have learned that life on earth
depends on temperature
light water air
and soil
living things cannot survive if it is
too
cold or if it is too hot
sun is the main source of fly plants use
sunlight to make food
[Music]
water air and soil are the most
important things for all the living
things on the earth
well done everyone see you in the next
video
till then take care allah face
