Question
What is the difference between autotrophic nutrition and heterotrophic nutrition?

Answer

Autotrophic Nutrition: It is that mode of nutrition in which an organism makes its own food from the simple inorganic materials like carbon dioxide and water present in the surroundings (with the help of sunlight energy)Example: Green Plants
Heterotrophic Nutrition: It is that mode of nutrition in which an organism cannot make its own food from simple inorganic materials like carbon dioxide and water, and depends on other organisms for its food.
Example: Animals.
