What do plants and animals need to grow?

Almost all plants and animals need air, water, light, and nutrition to grow.

Green plants use a complicated chemical process, called photosynthesis, to create energy for survival and growth.

Since plants create their own energy, they are the first link in the food chain.

Animals need to drink water and eat plants or other animals to get energy. Therefore, they are present at the next step in the food chain.

There are some animals, like camels, that can survive for days without drinking water. Since they live in deserts with very little water, they have adapted to the special conditions of their habitat.
