Heterotrophs

What is Heterotrophs? (hetero- others , trophs- food). The plants or living organism which doesn’t make their own food and will depend on another living organism is called heterotrophs and the nutrition which will gain by eating another living organism is called heterotrophic nutrition.

• Example : All animals , birds , aquatic animal and some plants ,etc

  • Types of Heterotrophic nutrition?

1) Holozoic Nutrition :

It is the type of heterotrophic nutrition in which another plant , animal and remain of plant and animal  is consumed. Holozoic nutrition is further divided into herbivores, carnivores, omnivores .

a) Herbivores: The animal which eats plants and are the primary organism of the food chain is known as herbivores animal.

Ex-Grass feeding animal – Cow , buffalo , plant eating insects- grasshopper etc.

b) Carnivores: The animals which eats other animal and are the secondary organism of food chain is known as carnivores animal.

Ex- Flesh eating animal – lion , tiger ,Flesh eating birds – hawk , eagle , owl etc

c) Omnivores : The animal which eats both plant and animal is known as omnivores animal.

Ex-Human being , some insects such as cockroach , some animals such as dog , bear etc.

2.) Parasitic Nutrition :

The organism which live in or on another living organism for food and shelter is known as parasite and the nutrition taken by one organism presenting in or on the body of an another living organism is called parasitic nutrition . The living organism on which parasite is present for food and shelter is called host .

Example – 1.) The mosquito is present on human and animal for sucking blood .

2.) Tapeworm is present in the intestine of  cow and pigs which feeds their undigested food particles.

3) Saprophytic Nutrition :

The organism which feed on the waste material of another organism is called saprophyte and the nutrition which is gain from the remain of an another organism is known as saprophytic nutrition .

Example – 1.) Mushroom gets nutrients from dead decaying plant material .

2.) Decomposers decomposes the dead animal body .

3.) Fungi grow on decade food get nutrients from that decaying food.
