Question

Q. 22. What are the differences between
autotrophic nutrition and heterotrophic nutrition ?​

Answer 1

Answer:

Autotrophic nutrition means that simple inorganic substances are taken in and used to synthesise organic molecules. Energy is needed to achieve this. In photo-autotrophic nutrition light is the energy source. In most instances the light source is solar energy, the process being photosynthesis.

Heterotrophic nutrition is a type of nutrition in which organisms depend upon other organisms for food to survive. Heterotrophic organisms have to take in all the organic substances they need to survive. All animals, fungi, and non-photosynthesizing plants are heterotrophic.

Answer 2

Answer:

Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition.”
