Question

Use an example to define and explain commensalism

Answer 1

Commensalism is a relationship between two organisms where one receives a benefit or benefits from the other and the other is not affected by it. In other words, one is benefited and the other is neither benefited nor harmed.

example
Tree frog - The frog uses plants or trees for protection from the rain

Answer 2

Commensalism is a symbiotic relationship in which one member benefits from the relationship, and the other is neither harmed nor does it benefit. Commensalism may be thought of as a positive-zero relationship in which one organism benefits, and the other is neither harmed nor hurt.

An example of commensalism is army ants that live in tropical areas. These army ants move across the rain forest and jungle and eat whatever they can find. Another kind of insect, a type of silverfish, marches right along with them. The silverfish are there in small numbers, and they don’t seem to compete for food with the army ants. The silverfish gain protection from predators by being in the midst of all the ants. They may get food left over from the ants. The silverfish benefit, while the army ants are neither harmed nor helped.
