Question

Barnacles are a type of arthropod in the subphylum Crustacea, and are related to crabs and lobsters. Barnacles are exclusively marine, tend to live in shallow and tidal waters, or attached to larger organisms. Barnacles are sessile; that means they do not move about. The image shows barnacles attached to the tail of a humpback whale. In this relationship, the barnacles derive benefit. There is not benefit or harm to the whale. This relationship is an example of

A) commensalism.
B) competition.
C) mutualism.
D) predation.

Answer 1

The answer is commensalism because commensalism is a relationship where an organism is benefitted and the other is neither benefitted nor harmed. The barnacle is being benefited and the whale is not being benefited or harmed.

Answer 2

Options-(A): Commensalism.

Step-by-step explanation:

As the barnacles are found on the skin of the whales, being attached to the mammal makes it easy for the barnacles to have more food and nutritional resources to live inside water. While, there is no benefit for the whales during such conditions as the barnacles nor provide nourishment to the specie nor it helps the whale to defend itself against any type of harm.Such relation between any two organisms is then termed as the commensalism by the professionals or we can say by the scientists who study such organisms.
