What do plants give us answer

1. Food:

  • Plants are the primary food source for all herbivorous animals.
  • During photosynthesis, they trap the maximum amount of energy from sunlight in their body.
  • As plants can make their food from the sunlight, they are called producers.
  • Plant-eating animals feed on plants and intake the energy trapped in the green plant’s body.
  • Carnivorous animals hunt herbivorous animals and feed on them; that is how they trap the energy inside their bodies.
  • Why is plant known as primary source of food
  • Apart from all these animals, humans and birds eat fruits, leafy vegetables, and other edible parts of the plant, like seeds and roots.
  • Plants also store food inside their different body parts—
    1. Carbohydrate is stored in potato, a tuber.
    2. We eat lentils that are plant seeds, rich in protein.
    3. Peanuts and walnuts are rich in fats.

Even humans utilise different parts of plants to construct their houses.
