N commensalism _________.

Answer 1

Answer:

A. the host and commensal can be separated and remain viabe

Explanation:

Commensalism is a  biological interaction ( i.e symbiosis) in which members of one species gain benefits while those of the other species neither benefit or are harmed.

The  species that benefits from the association in order to obtain nutrients, shelter, support, or locomotion from the host species is known as the Commensal. The commensals are usually unaffected.

The Host species is usually a larger animal. An example of commensal interaction with it host species can be found between shark and remora fish. The remora fish attachs itself to the shark in order to engulf remnant of food materials eaten by the shark and also to be protect BUT at the same time that doesn't makes remora to be attached forever to shark,the commensal can detach whenever it wants to.

Another example can be distinguished from birds (commensal) and grazing herbivorous animal (host). Numerous birds perch on bodies of large mammal herbivores or feed on the insects turned up by grazing mammals BUT the host and commensal can be separated and remain viabe.
