Question

what are the different between autotrophic nutrition and heterotrophic nutrition?​

Answer 1

Explanation:

Autotrophs and heterotrophs are the two classifications of organisms on the basis of nutrition. Autotrophs are organisms that can prepare their own food. On the contrary, heterotrophs depend on autotrophs and other organisms for nutrition.

★ Autotrophic Nutrition

$\longrightarrow$ The organisms that make their food from simple inorganic substances are called autotrophs, g., most green plants. Therefore, autotrophic nutrition refers to the process of nourishing, namely photosynthesis, that organisms adopt for growth and maintenance.

$\longrightarrow$ The raw materials required for preparation of food are CO, and H₂O.

$\longrightarrow$ Chlorophyll and sunlight are essential for photosynthesis and thus nutrition to occur.

★ Heterotrophic Nutrition

$\longrightarrow$ The organisms which cannot make their own food and depend directly or indirectly on autotrophs for their survival are called heterotrophs, eg, animals and fungi.

$\longrightarrow$ Heterotrophic nutrition refers to the process of nourishing, namely by obtaining food from other organisms, for their own growth and maintenance.

$\longrightarrow$ Heterotrophs are directly or indirectly dependent on autotrophs.

$\longrightarrow$ Chlorophyll and sunlight are not required.
