If the vegetation of a place is burnt the first one to appear will be

Options

A. Mosses
B. Lichens
C. Liver worts
D. Grasses

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what the first organisms to appear are after the vegetation of a place is burnt. This situation leads to a process known as ecological succession.

2. **Defining Ecological Succession**: When an area experiences a disturbance, such as burning, ecological succession occurs. This is a series of changes in the composition of species in a particular area over time.

3. **Identifying Pioneer Species**: In ecological succession, the first species to colonize a disturbed area are known as pioneer species. These species are specially adapted to survive in harsh conditions, such as bare or burnt land.

4. **Analyzing the Options**:
- **Mosses**: These are not typically the first to appear after a disturbance; they are usually part of later stages in succession.
- **Lichens**: These are known to be pioneer species. They can survive in extreme conditions and can grow on bare rock or burnt soil.
- **Liverworts**: Similar to mosses, these are not pioneer species and usually appear after lichens.
- **Grasses**: These are also not the first to appear; they come in later stages of succession.

5. **Conclusion**: Based on the analysis, the first organisms to appear after the vegetation of a place is burnt are **lichens**.

**Final Answer**: The first one to appear will be **lichens**.
