Question

how do organism obtain their Nutrition

Answer 1

Autotrophic organisms make theirown food by a process called photosynthesis. Green plants, for example, manufacture sugar and starch from carbon dioxide and water using the energy of sunlight to drive the necessary chemical reactions. Heterotrophic organisms obtain theirfood from the bodies of otherorganisms.

Answer 2

Therefore they cannot make food from carbon dioxide and water. This means that animals must get theirfood from other organisms, such as plants or other animals. Like plants and algae, animals use food to produce different kinds of substances after they eat it. Animals use these substances for energy.
