SYMBIOTIC NUTRITION. What is symbiotic nutrition?
Symbiotic nutrition is a type of nutrition in which two organisms of different species called SYMBIONTS live together and derive nutrients or food from each other.
how does symbiotic nutrition work
In symbiotic nutrition, both organisms gain from such association and none is harmed. This type of nutrition called symbiotic nutrition while the association between the two organisms in which both derive benefits is called SYMBIOSIS
benefits of symbiotic nutrition
Apart from the nutritional benefits, the symbionts can derive other benefits like protection, reproduction shelter during such association
Examples of symbiotic nutrition
Examples of organisms that exhibits symbiotic feeding are
1. Nitrogen fixation bacteria and root nodules of leguminous plants
2. Algae and Fungi in a lichen
3. Sea anemones and hermit crabs
4. Termites and protozoa living together in the gut
NITROGEN FIXATION BACTERIA AND ROOT NODULES OF LEGUMINOUS PLANTS IN SYMBIOTIC NUTRITION
a typical example of symbiotic nutrition and association is the one between nitrogen fixing bacteria, Rhizobium spp and the root nodules of leguminous plants.

The bacteria is able to fix atmospheric nitrogen directly into the plant while the plant provide shelter and food for the bacteria.
FUNGI IN LICHEN A TYPE OF SYMBIOTIC NUTRITION
a LICHEN is usually made up of two organisms, a fungus and a unicellular Alga, living closely together and this an example of symbiotic nutrition.
The thallus or plant body of a lichen consists mostly of fungal hyphae, with alga cells embedded in them.
The alga cells are arranged in a definite layer. The green alga manufactures food for both plants, while the fungus protects the alga and absorbs water from the surroundings— osmosis and diffusion. thereby making the symbiotic nutrition process complete.
SEA ANEMONES AND CRABS A TYPE OF SYMBIOTIC NUTRITION
in this type of symbiotic feeding, the sea anemone is known to attach itself to the empty shell in which the hermit crab is found. Pieces of food left by the hermit crab is what the sea anemone eats.
The hermit is protected from predators that would have attacked or eaten it as the sting of the sea anemone keep them away from the hermit crab
4. TERMITES AND PROTOZOA LIVING TOGETHER IN THE GUT
Symbiotic feeding 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:
- 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.
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
