Did it on AP5X

Lichens prepare bare rock to support the growth of plants by releasing acids that help break down the rock to form soil. Thus, the correct option for this question is B.

Lichens may be defined as a complex life form that is a symbiotic partnership of two separate organisms, a fungus, and an alga. In this symbiosis relationship between two organisms, the dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies.

Lichens are important as early-stage primary succession organisms. They are keystone species in many ecosystems. They serve as a food source and habitat for many animals such as deer, birds, and rodents. They provide nesting materials for birds. They protect trees and rocks from extreme elements such as rain, wind, and snow.

Lichens contribute to soil formation by decomposition as well. There are two primary types of decomposition that contribute to the formation of soil: in-situ decomposition and litterfall.

Therefore,  the correct option for this question is B.
