Enlist the examples for the different types of heterotrophic mode of nutrition
1. Nitrogen fixation
Answers
Answer:
Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.”
Types of Heterotrophic Nutrition
In nature, organisms exhibit various types of heterotrophic nutrition. They are as follows:
Holozoic Nutrition
Saprophytic Nutrition
Parasitic Nutrition
Holozoic Nutrition
Holozoic nutrition involves the ingestion and internal processing of solid and liquid food in an organism. This involves the steps of ingestion, digestion, absorption, assimilation and excretion.
Saprophytic Nutrition
Saprophytes (animals which follow saprophytic nutrition) feed on dead and decayed organisms for energy. They are an important part of the ecosystem as they help to keep our environment clean and recycle nutrient back into the ecosystem.
Parasitic Nutrition
Organisms that live in or on other organisms and acquire food at the expense of its host are called parasites. Most parasites are harmful to the hosts’ health; sometimes, they even kill the host. Both animals and plants may serve as a host. Unlike commensalism, the parasite causes some harm to its host. A few examples of parasites are louse on a human head, Cuscuta plant and tapeworms.
