Question

How does food yield energy?

Answer 1

Answer:

Food is the main "source of energy" for all the living things like plant, animals and humans. They all required food to carry out their daily life process and to live.

EXPLANATION:

    Plants are known as autotrophs it means that they produce their food through the process of photosynthesis. Animals and humans are 'heterotrophs' because they can't produce their own food and they are dependent on other for the requirement of food.

   The food produced through the photosynthesis converted into glucose and then into starch which is used by the plant for various purposes for like growth.

    When humans and animals eat food, through the process of metabolism it is converted into energy and transferred into cell for their process. The cell takes this energy and uses it for surviving and doing various activities.
