The growth of mosses and lichens on a bare volcanic region helps prepare the area for the next stages of succession. How do mosses and lichens most contribute to this process? Asap

A.
They poison populations of primary consumers.

B.
They build up soil deposits on the rocky ground.

C.
They neutralize deposits of extreme acids in the rocks.

D.
They increase the amount of oxygen in the surrounding air.

The correct answer is - B. they build up soil deposits on the rocky ground.

Explanation:

Lichens and mosses are known as the pioneer species as they prepare the particular region for the next stages of succession on the bare volcanic region. Lichens and mosses grow on the bare rocks and secrete acids to break the rocks and start soil production.

The soil deposits produced by breaking the volcanic rocks by secreting acids from mosses and lichens. Even after dying these species leads to thickening of the soil and increase organic matter for the next stages to grow.
