An insect that has evolved to resemble a plant twig will probably be able to avoid A) parasitism. B) symbiosis. C) predation. D)
bagirrra123 [75]

Answer:

C) predation

Explanation:

Such an insect would serve as a prey to a predator in a prey-predator relationship. Such relationship is a predation.

Predation is an act of feeding in a prey. The preys are weaker and smaller organisms which can easily be overpowered by the bigger predators.

When an insect evolves to resemble a plant twig, it is an evolutionary mimicry. Such organism that evolves must be prey. This presents the prey an evolutionary advantage for it to be evaded by the devouring predator. Mimicry is an evasive tactics.

In parasitism, one organism benefits while the other, the host, suffers from the relationship. Here, the parasite is lives inside the host. A mimicry won't apply here.
