Question

Define autotrophic mode of nutrition. Write an example of autotrophs.​

Answer 1

Answer:

Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.” The term “autotrophic” is formed by the combination of two terms, “auto” meaning self, and “trophic” meaning nutrition.

Seaweeds are algae. Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.

Answer 2

Answer:

It refers to mode of nutrition in which the organisms are able to make their own food by using simple substances . Eg- green plants are autotrophs as they make their own food by using CO2 and water.
