Question

A keystone species is removed from an ecosystem. This will not cause

• A. Decrease in species diversity
• B. Increase in the rate of growth of one or more populations
• C. Increase in other community populations
• D. Decrease in the carrying capacity for most of the community
• E. Increase in the types of ecological interactions

Answer 1

Answer: (B)

If a keystone species is removed from an ecosystem there will not be any more increase in the rate of growth of one or more populations.

A keystone species is any plant or animal species that can control pollution and maintains ecosystem. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. All species in an ecosystem, or habitat, rely on each other.

Thus, the correct answer is option E.
