Question

A mite is a tiny organism that may "ride" on top of an insect such as a beetle in order to move quickly from place to place.

This relationship between the mite and the beetle would be an example of mutualism if
A.
the beetle eats the mite.
B.
the mite protects the beetle from predators.
C.
the beetle is neither harmed nor helped by the mite.
D.
the beetle is unable to catch prey because it is slowed down by the mite.

Answer 1

B

Mutualism is a relationship where both species benefit. If the mite gains transport and also protects the beetle from predators, both benefit. Options A and D involve harm to the mite or beetle, and C is commensalism.
