Answer:
D.
Step-by-step explanation:
Unlike the fruits that the animals have eaten, the seeds do not get digested and instead pass through the digestive track intact. Once the fruit is eaten by the animal the seeds will be deposited in the animal's waste so that they can grow into a new blackberry plant. The waste actually acts as a fertilizer which helps the seed grow once it falls into the ground where it can get the rest of the resources it needs to grow properly. This is one of many ways that animals help plants grow.
