Question

a species of bee that is the sole pollinator for a specific type of flower is classified as a keystone species. which of the following best explains the rationale behind the classification? a. it is a common species that can be found in many different biomes. b. its presence is vital for the survival and stability of the entire ecosystem. c. it is a species that has been introduced to the ecosystem from a foreign location. d. it is an indicator of the overall health of a specific population.

Explanation:

A keystone species has a disproportionately large impact on its ecosystem relative to its abundance. Its presence is crucial for the survival and stability of the entire ecosystem. Option A is about a common - distributed species, not the definition of a keystone species. Option C describes an introduced species, which is not related to the concept of keystone species. Option D refers to an indicator species, not a keystone species.

Answer:

B. Its presence is vital for the survival and stability of the entire ecosystem.
