Question

difference between autotrophic nutrition and heterotrophic nutrition?

Answer 1

There are two process by which organisms obtain nutrition . One is the autotrophic nutrition and the other is heterotrophic nutrition .
Autotrophic Nutrition In autotrophic nutrition organism prepares its food from simple substances present in the surroundings .
Heterotrophic Nutrition In heterotrophic nutrition organism obtains food from digesting organic compounds .
Autotrophic Nutrition Autotrophs are the producers in the food chain .
Heterotrophic Nutrition Heterotrophs are the consumers in the food chain .
Autotrophic Nutrition Example : Plants obtain food by autotrophic nutrition .
Heterotrophic Nutrition Example : Some plants and all animals obtain food by heterotrophic nutrition .
Autotrophic Nutrition utotrophs are fundamental to the food chains of all ecosystems in the world. They take energy from the environment in the form of sunlight or inorganic chemicals and use it to create energy-rich molecules such as carbohydrates. This mechanism is called primary production.
Heterotrophic Nutrition Other organisms, called heterotrophs, take in autotrophs as food to carry out functions necessary for their life. Thus, heterotrophs — all animals, almost all fungi, as well as most bacteria and protozoa — depend on autotrophs, or primary producers, for the energy and raw materials they need.
Autotrophic Nutrition Types of Autotrophic nutrition: (i)Phototrophic (ii) Chemotrophic
Heterotrophic Nutrition Types of Heterotrophic nutrition : (i) Holozoic (ii) Saprophytic (iii)Parasitic and (iv) Symboitic Association
