Answer:
You have learnt that all living
organisms require food. Plants can make
their food themselves. Can you recall
how green plants synthesise their own
food? Animals including humans can
not make their own food. So, where do
animals get their food from?
But, first of all why do we have to eat
food?
You already know that energy from
the food is utilised by organisms for
carrying out their various body
functions, such as digestion, respiration
and excretion. We get our food from
plants, or animals, or both.
Since we all need food,
how can we provide
food to a large number
of people in our
country?
Food has to be
produced on a large
scale.
I want to know
where and how we
use these tools.
