What is the difference between parasites and heterotrophs?
Parasites are those organisms that may live inside the other organism’s body or on their surface to obtain nutrition, causing harm to the host. In a few parasitic relationships, the host dies while in others, it is important that the host remains alive.
They exhibit a parasitic mode of nutrition, which is one of the modes of nutrition of heterotrophs.
Example: Fleas and mosquitoes feed on blood from other organisms.
In this type of parasitic relationship, the host needs to stay alive and it is not damaged greatly.
Heterotrophs- Organisms depending on plants and other animals for nutritional requirements are known as heterotrophs, and they exhibit a heterotrophic mode of nutrition. For example, humans, animals, birds, etc.
Heterotrophs can be further classified into three different types based on their modes of nutrition.
i) Holozoic nutrition- In holozoic nutrition, organisms feed by ingesting solid material, and later digesting them in the digestive tract.
Examples include- humans, animals, insectivorous plants.
ii) Saprophytic nutrition- In this, the organisms feed on dead and decaying matter. For Example, bacteria, and fungi digest the food externally and then absorb the nutrients.
iii) Parasitism- This type of nutrition is seen in parasites. As parasites live on or inside a living host, they absorb food and other nutritional requirements from the host. Examples, lice, tapeworms, etc.
