Question

question 9. the first organisms to occupy an area after a prairie fire are known as a. primary species. b. secondary species. c. succession species. d. pioneer species.

Explanation:

In ecological succession, pioneer species are the first to colonize an area after a disturbance like a prairie fire. They are hardy and can grow in harsh conditions, paving the way for other species. Primary and secondary species refer to later - stage species in succession, and "succession species" is a more general term that doesn't specifically denote the first - arriving ones.

Answer:

D. pioneer species
