Question

when two different species live in close relationship with one another, usually such that one species depends on the other for food or shelter, its called a symbiotic relationship. what kind of symbiotic relationship it is depends on which species in the relationship is harmed or benefited.

parasitism describes a relationship in which one species benefits while the other is harmed. fleas and ticks are parasites. they gain nourishment and shelter while exposing their host to disease and discomfort. under mutualism, by contrast, both species benefit. for example, the oxpecker bird eats lice and ticks off the skin of an elephant, getting food for itself while also relieving the elephant of irritating parasites. finally, in commensalism, one species benefits while the other is neither harmed nor helped. mites living in human hair follicles, for example, enjoy their food and shelter but go unnoticed by humans.

which term matches the picture?

image of a mosquito

parasitism commensalism mutualism

Explanation:

The picture shows a mosquito, which benefits by getting blood (nourishment) from a human/animal host, while the host is harmed (exposed to disease, discomfort). This matches parasitism (one benefits, one is harmed), unlike commensalism (one benefits, other unaffected) or mutualism (both benefit).

Answer:

parasitism
