Question

Give one point of difference between autotrophic and heterotrophic nutrition

Answer 1

Answer:

Autotrophic Nutrition Heterotrophic Nutrition

In autotrophic nutrition organism prepares its food from simple substances present in the surroundings . In heterotrophic nutrition organism obtains food from digesting organic compounds .

Autotrophs are the producers in the food chain . Heterotrophs are the consumers in the food chain .

Example : Plants obtain food by autotrophic nutrition . Example : Some plants and all animals obtain food by heterotrophic 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. 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.

Types of Autotrophic nutrition: (i)Phototrophic (ii) Chemotrophic Types of Heterotrophic nutrition : (i) Holozoic (ii) Saprophytic (iii)Parasitic and (iv) Symboitic Association

Answer 2

Hello Friends,

◆ Autotrophic vs heterotrophic nutrition -

1. In autotrophic nutrition, organisms produce their own food while no such thing is possible in heterotrophic nutrition.
2. Autotrophs are primary producers while heterotrophs are consumers.
3. Autotrophs food production is independent whereas heterotrophs are directly/independently dependent on autotrophs for food.
4. Autotrophs use raw matetials like CO2, water, minerals to prepare food while heterotrophs consume readymade food for nutrition.
5. Autotrophs include plants, algae & bacteria while heterotrophs include fungi & animals.

Hope this helped.
