Question

Select the correct answer. Mycorrhizae are associations formed by fungi that grow on the roots of trees. These fungi penetrate into the roots of the trees. The trees produce energy through photosynthesis and share it with the fungi. The fungi act as decomposers, breaking down dead organic matter to provide nutrients for the trees to grow. What kind of a relationship is exhibited in this example?

A.
The fungi share a mutualistic association with the trees.
B.
The fungi are a parasite for trees.
C.
The fungi share a commensal association with the trees.
D.
The fungi are predators for the trees.

Answer 1

A. The fungi share a mutualistic association with the trees.

Step-by-step explanation:

Mutualistic relationship is a type of ecological interaction in which two species live in close association to benefit each other. In this example since both mycorrhizae and fungi are being benefited out of each other it is mutualistic relationship. The fungi gets energy from the tree for its survival and in return breaks down dead organic matter for the tree so as to make nutrients available for the tree.
