Which is correct regarding keystone species?

A. Keystone species cannot be mutualists with other species.
B. Keystone species are often abundant individuals in a community.
C. Keystone species are most likely to be commensalists.
D. Some keystone species are habitat engineers.

The correct statement is that some keystone species are habitat engineers. Keystone species have a significant impact on their ecosystem's biodiversity and structure, as exemplified by the intertidal sea star and the banded tetra.

Explanation:

Regarding keystone species, the correct statement is that some keystone species are habitat engineers. A keystone species plays a crucial role in maintaining biodiversity within an ecosystem and the structure of an ecological community. One example is the intertidal sea star, Pisaster ochraceus, in the northwestern United States. When removed, the mussel population, their natural prey, increases, which then drastically changes the species composition and reduces biodiversity. Similarly, the banded tetra, a fish in tropical streams, supplies almost all of the necessary inorganic nutrient phosphorus to its community and greatly impacts the ecosystem.
