Question

Write short notes on:
Heterotrophic nutrition

Hint:

Heterotrophic organisms depend on plants or other animals for energy and survival.

Answer 1

Heterotrophic nutrition is a mode of nutrition in which organisms depend on other organisms for food because they cannot produce their own. It includes holozoic nutrition (e.g., humans, animals), saprophytic nutrition (e.g., fungi, bacteria), and parasitic nutrition (e.g., leeches, tapeworms).
Example: Humans and animals consume plant and animal matter for energy, while fungi decompose dead matter.
