Answer:
The correct answer is B. Predation.
Step-by-step explanation:
Predation is a special case of heterotrophy. A predator is therefore an organism that lives by hunting, killing and consuming all or part of other organisms. Predators that are at the top of the food chain are often called top consumers or top predators, while those that are further down the ladder are called mesopredators. Predation can also to some extent be compared to parasitism, but differs from parasitism in that parasites do not kill the prey, at least not in the short term.
