AUTOTROPHIC NUTRITION

HETEROTROPHIC NUTRITION

v Food is synthesized by autotrophic organisms like plants, using water, minerals, CO₂ in the presence of sunlight and chlorophyll.

v Plants and few bacteria perform autotrophic nutrition.

v Chlorophyll (green pigment) is necessary.

v Heterotrophic nutrition is obtaining food from the heterotrophs, since it cannot synthesize its own food.

v Animals and some fungi have heterotrophic nutrition that cannot make their own food.

v Chlorophyll (green pigment) is not required.
