Mutualism is a symbiotic relationship in which both organisms benefit from each other. In the case of a bee pollinating a flower, the bee gets nectar and pollen from the flower, and the flower gets its pollen distributed to other flowers, which helps it to reproduce.

Commensalism is a symbiotic relationship in which one organism benefits from the other without harming it. In the case of a barnacle living on a whale, the barnacle gets a place to live and grow, while the whale is not affected by the barnacle.

Parasitism is a symbiotic relationship in which one organism benefits from the other at the expense of the other. In the case of a tapeworm living in a human intestine, the tapeworm gets nutrients from the human's food, while the human is harmed by the tapeworm.

Commensalism is a symbiotic relationship in which one organism benefits from the other without harming it.

Parasitism is a symbiotic relationship in which one organism benefits from the other at the expense of the other.

Amensalism is a symbiotic relationship in which one organism is harmed by the other.

Amensalism is a symbiotic relationship in which one organism is harmed by the other. In the case of a tree shading out a smaller plant, the smaller plant is harmed by the tree's shade.

A symbiotic relationship is a close relationship between two different organisms. In the case of a bee pollinating a flower, the bee gets nectar and pollen from the flower, and the flower gets its pollen distributed to other flowers, which helps it to reproduce.

A mutualistic relationship is a symbiotic relationship in which both organisms benefit from each other. In the case of a bee pollinating a flower, the bee gets nectar and pollen from the flower, and the flower gets its pollen distributed to other flowers, which helps it to reproduce.

An amensalistic relationship is a symbiotic relationship in which one organism is harmed by the other. In the case of a tree shading out a smaller plant, the smaller plant is harmed by the tree's shade.

A neutralistic relationship is a symbiotic relationship in which neither organism is affected by the other. In the case of two species of bacteria living in the same environment, neither species is affected by the other.

A facultative symbiotic relationship is a symbiotic relationship in which one or both organisms can survive without the other. In the case of a bee pollinating a flower, the bee can survive without pollinating flowers, and the flower can survive without being pollinated by bees.
