Question

what is the role of a pioneer species in primary succession?
○ to destroy parasites
○ to provide shade
○ to provide fruit
○ to produce the soil

Explanation:

In primary succession, pioneer species (like lichens, mosses) colonize barren areas (e.g., bare rock). They break down the rock through processes like weathering, and when they die, their organic matter contributes to forming soil. Destroying parasites isn't their role. Providing shade or fruit happens later in succession with more complex plants. So the role of pioneer species is to produce soil.

Answer:

to produce the soil
