Q.1 Why do organisms need to take food?

Answer :

1.All organisms require energy for their life process which they get from food.
Thus food is essential for all organisms.

2.Carbohydrates, proteins, fats, vitamins, and minerals are components of food.
These components of food are called nutrients and are necessary for our bodies.

3.Plants can synthesize food for themselves and acquire nutrients from abiotic components
but animals including humans cannot. They get it from plants or animals that eat plants.
Thus, humans and animals are directly or indirectly dependent on plants.
