Question

When both partners/components are affected negatively, the nature of interaction is

• A. Commensalism
• B. Predation
• C. Competition
• D. Amensalism

Answer 1

Answer: (C)

Competition

When both partners/components are affected negatively, the nature of the interaction is competition. Competition is an interaction between organisms or species in which the fitness of one is lowered by the presence of another. The limited supply of at least one resource (such as food, water, and territory) used by both can be a factor.

Predation is a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked).

Amensalism is any relationship between organisms of different species in which one organism is inhibited or destroyed while the other organism remains unaffected.

In commensalism, one organism benefits from the relationship while the other species involved neither benefits nor is harmed.

So, the correct answer is option C.
