Which of the following is not an example of predation?

a. a blue whale feeding on zooplankton

b. a tree obtaining nutrients from the soil

c. a caterpillar eating the leaves of a tree

d. a wolf eating a deer

The answer is b.A tree obtaining nutrients from the soil. A prey is an organism that is being eaten by another organism called a predator. It is known that plants are able to produce food on their own and they do not eat other organisms. So, plants cannot be predators which suggest that choice b. is correct. On the contrary, a blue whale, a caterpillar, and a wolf eat other organisms, so they are examples of predators.
