What is symbiotic nutrition?

Symbiotic nutrition is the relationship between two organisms in which they are mutually benefited by sharing their nourishment and shelter.

This mutual relationship may or may not be beneficial to both organisms.

There are mainly 3 types of symbiotic relationships:

1. Commensalism- It is the mutual relationship where only one of the organisms gets benefit while other doesn't get benefited. It is a one-sided symbiotic relationship.

Example: Relationship between remora fish and large fishes. Remora fish attach to larger animals, like sharks, and whales with the help of disk present on their heads and moves with them. When the larger animals feed, the remora fish detaches itself to eat the extra food.

2. Parasitism- It is the mutual relationship where one of the organisms get benefited while others get harmed.

In this, one organism may live inside the other organism’s body or on its surface. In a few parasitic relationships, the host dies while in others, it is important that the host remain alive.

Example: Fleas and mosquitoes feed on blood from other organisms.

3. Mutualism- It is the mutual and close relationship where both the organisms get the benefit.

Example: Rhizobium living in the root nodules of leguminous plants.

Dogs and humans have enjoyed a mutualistic symbiosis for centuries. The dogs supply protection and companionship and humans provide food and shelter.
