Question

which of the following best describes the term extinction? choose 1 answer: a a risk to a species from environmental changes that are due to human activities b the loss of an individual because it is poorly suited to its environment c the dying out of a group of organisms due to the groups inability to survive and reproduce

Explanation:

• Option A describes a human - caused risk to a species, not extinction itself. Extinction is about the group (species) dying out, not just a risk.
• Option B describes the death of an individual due to being poorly adapted, which is not extinction. Extinction involves a whole group.
• Option C correctly defines extinction as the dying out of a group of organisms because the group cannot survive and reproduce.

Answer:

C. the dying out of a group of organisms due to the group’s inability to survive and reproduce
