Mutualism, commensalism, and parasitism are the three types of a. symbiotic relationships b. predation c. competition d. prey adaptations

Answer : The right answer is -

a. Symbiotic relationships.

Symbiotic relationship can be described as a long term, close biological association between two organisms, which belong to same or different species.

There are primarily three types of symbiotic relationships that are-

1) Mutualism- When both the interacting organisms are benefited.

2) Commensalism- When one organism gets benefit while other is neither benefited nor harmed.

3) Parasitism - When one organism is benefited (Parasite) and the other organism is harmed (host).

Thus, option a) is the right answer.
