(a) What are heterotrophs? Give one example of heterotrophs.
(b) What is the difference between autotrophic nutrition and heterotrophic nutrition?
(a) Those organisms which cannot make their own food from inorganic substances like carbon dioxide and water, and depend on other organisms for their food are called heterotrophs.
Example: All Animals.
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.
