Answer:

D. Its extinction would cause a significant change in the community.

Explanation:

A keystone species is a species that helps define an entire ecosystem. If its keystone species disappeared, the ecosystem would significantly change or even disappear, too.

There are several types of keystone species:

  • Predators - they help control the populations of other species, e.g. sharks.
  • Engineers - they create, change, or destroys a habitat, e.g. beaver.
  • Mutuals - two or more species interact for each other’s benefit, e.g. bees and flowers.

Based on this information, we can conclude that the correct option is D.
