In mutualism, both organisms benefit from the association. In the case of a bee pollinating a flower, the bee gets nectar and pollen from the flower, while the flower gets its pollen distributed to other flowers, which helps it to reproduce.

Trophallaxis is a type of mutualistic relationship in which one organism provides food for the other. This is often seen in social insects, such as ants and bees, where workers share food with the queen and other members of the colony.

Lichen is a mutualistic relationship between a fungus and an alga. The fungus provides a home for the alga, while the alga provides food for the fungus through photosynthesis.

Inquilinism is a type of mutualistic relationship in which one organism provides shelter for the other. This is often seen in animals, such as birds that build nests in trees, or fish that live in coral reefs.

In mutualism, both organisms benefit from the association. In the case of a bee pollinating a flower, the bee gets nectar and pollen from the flower, while the flower gets its pollen distributed to other flowers, which helps it to reproduce.

Phoresy is a type of mutualistic relationship in which one organism provides transportation for the other. This is often seen in animals, such as mites that attach themselves to insects or birds, or barnacles that attach themselves to whales.

In mutualism, both organisms benefit from the association. In the case of a clownfish and a sea anemone, the clownfish gets protection from predators by living in the sea anemone's tentacles, while the sea anemone gets food from the clownfish's waste.

Mutual grooming is a type of mutualistic relationship in which one organism provides a service for the other, such as grooming each other's fur or feathers.

Mycorrhizae is a type of mutualistic relationship between a fungus and an animal. The fungus provides the animal with nutrients, while the animal provides the fungus with a home.

Chemical mimicry is a type of mutualistic relationship in which one organism provides a chemical benefit to the other, such as producing a chemical that attracts prey or repels predators.

Nitrogen fixation is a type of mutualistic relationship between a bacterium and an animal. The bacterium provides the animal with nitrogen, which is essential for plant growth, while the animal provides the bacterium with a home.

Structural support is a type of mutualistic relationship in which one organism provides a physical benefit to the other, such as providing support for a plant or an animal.

Zooxanthellae is a type of mutualistic relationship between a protist and an animal. The protist provides the animal with food through photosynthesis, while the animal provides the protist with a home.

Pollination is a type of mutualistic relationship in which one organism provides a reproductive benefit to the other, such as pollinating a flower or dispersing seeds.

Lysogeny is a type of mutualistic relationship between a virus and a bacterium. The virus integrates its DNA into the bacterium's DNA, and the bacterium provides the virus with a home.
