Answer 1

A pioneer species is a species that establishes in a new, barren environment first.

Step-by-step explanation:

The best statement that describes a pioneer species is b) A species that establishes in a new, barren environment first. A pioneer species is the first species to appear in primary and secondary succession on new or disturbed land. They are able to colonize landscapes devoid of soil and begin the process of succession. Examples of pioneer species include lichens and certain plants that can grow and reproduce quickly in harsh environments.
