Answer:
D.
Step-by-step explanation:
When two organisms are in a mutualistic relationship, they benefit each other in a way that both rely on each other for survival in a particular environment. The elimination of one of them might have a negative effect on the survival of the other.
So also, the development of new resorts in the area which leads to the detsruction of the Hawaiian silverswords will therefore have a negative effect on the population of the honeycreeper. The population of the Honeycreeper will decrease because they rely on the silverswords for survival.
