a. mutualism
b. competition
c. commensalism
d. parasitism

Explanation:

Question 1

Mutualism is a symbiotic relationship where both species involved benefit. Competition is when species compete for resources, parasitism is when one benefits and the other is harmed, and commensalism is when one benefits and the other is unaffected. So the correct option is a.

In a predator - prey relationship, if the number of predators increases, they will consume more prey, so the prey population will decrease (not necessarily exponentially or go extinct immediately, and it won't increase or stay constant). So the correct option is a.

Interspecific competition occurs when two different species compete for the same limited resource. Facilitation is a positive interaction, commensalism is one - sided benefit, and mutualism is both - sided benefit. So the correct option is d.

Answer:

a. Mutualism
