Barnacles and whales have a commensalistic relationship in which barnacles benefit. what would most likely happen to the whale population if the barnacle population decreased? become extinct decrease increase stay the same

stay the same

Explanation:

Commensalism can be define as relationship between two organisms which lives in close association with each other. In this relationship one organism is benifited and the other is neither harm or benifited.

The barnecal is the lice which attach themselves to the whale skin which sucks the blood. But whale having a large body remain unaffected.

On the basis of the above description, if the barnecle population decrease than the whale population will remain the same.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
