The given question is incomplete as it does not have the options which are:
A. commensalism
B. mutualism
C. parasitism
D. predator-prey
Answer:
B. mutualism
Explanation:
The species in the ecosystem interact with each other in many ways and one such type of interaction in which both the species are equally benefitted is known as the mutualism.
When one species provides benefit to second species whereas the second species provides benefit to the first species in a way that the evolution has transformed the relationship into an inseparable or highly dependent relationship.
