Specialist species are more susceptible to being wiped out by the introduction of invasive species.

The blackspot fungus serves as a bioindicator.

Primary succession starts from bare rock.

A population is a group of individuals of the same species living in the same area and interbreeding.

True.

Generalist species can thrive in a wide range of environmental conditions.

Genetic variation is essential for evolution as it provides the raw material for natural selection.

A sea otter is an example of a keystone species; it plays a critical role in maintaining the structure of its ecosystem.

Primary succession occurs on bare rock or lifeless areas, while secondary succession occurs in areas where a disturbance has destroyed an existing community but soil and some organisms still remain.

Invasive species can disrupt local ecosystems, outcompete native species, and lead to biodiversity loss.
