The keystone hypothesis states that each species plays a small, but important role in the health of an ecosystem. This is evident in the research on keystone species, which have a disproportionate impact on the ecosystem relative to their abundance. This statement aligns with the idea that the loss of even a single species can have significant effects on the functioning and health of the ecosystem. Therefore, choice A is the most accurate statement in accordance with the keystone hypothesis.
