Study Notes
Modes of Nutrition in Living Organisms
-
Organisms obtain food through two primary modes: autotrophic and heterotrophic nutrition.
-
Autotrophic Nutrition
- Derived from Greek terms 'auto' meaning self and 'trophic' meaning nutrition.
- Autotrophs can synthesize their own food from inorganic materials.
- Examples include all green plants, which utilize photosynthesis, and green algae.
-
Heterotrophic Nutrition
- Originates from Greek terms 'hetero' meaning other and 'trophic' meaning nutrition.
- Heterotrophs cannot produce their own food and rely on other organisms for energy.
- Examples encompass all animals, non-green plants, and fungi, which consume organic matter.
