A keystone species is always a good indicator species.

Question

Quizplus · Accepted Answer

A keystone species is defined as a species that has a disproportionately large effect on its environment relative to its abundance. While a keystone species may be an important indicator of the health of an ecosystem, it is not always a good indicator species because its presence or absence may not reflect the overall health of the ecosystem. Other factors, such as environmental conditions and human activities, can also impact the health of an ecosystem, making it important to use multiple indicator species.
