Growth of lichens on barren rocks is followed by the growth of

Options

A. moss
B. ferns
C. gymnosperms
D. algae

Explanation

**Step-by-Step Solution:**

1. **Understanding Lichens**: Lichens are a symbiotic relationship between fungi and algae. They can grow in harsh environments, such as barren rocks.

2. **Role of Lichens**: When lichens grow on barren rocks, they contribute to the weathering of the rock. They secrete enzymes that help break down the rock material.

3. **Formation of Soil**: As lichens break down the rock, they create a thin layer of soil. This soil is essential for the growth of other organisms.

4. **Next Stage of Growth**: The presence of lichens and the soil they help create allows for the growth of mosses. Mosses are the next organisms to colonize the area after lichens.

5. **Further Succession**: Once mosses establish themselves, they can further contribute to soil formation and create conditions suitable for the growth of higher plants, such as ferns and gymnosperms.

6. **Conclusion**: Therefore, the growth of lichens on barren rocks is followed by the growth of mosses.

**Final Answer**: The growth of lichens on barren rocks is followed by the growth of **mosses**.
