Climax community in xerarch succetssion comprises of

Options

A. Lichens only
B. Shrubs only
C. Shrubs and trees
D. Lichens and bryophyts

Answer

### Step-by-Step Solution:

1. **Understanding Xerarch Succession**:
- Xerarch succession refers to the ecological succession that occurs in dry or barren environments, where the initial colonizers are adapted to survive in low moisture conditions.

2. **Identifying the Climax Community**:
- A climax community is the final stage of ecological succession, where the ecosystem becomes stable and sustainable. In xerarch succession, this community is characterized by specific types of vegetation.

3. **Pioneer Species**:
- The first organisms to inhabit barren land are known as pioneer species. In xerarch succession, lichens are typically the first to colonize the area, as they can survive in harsh, dry conditions.

4. **Progression of Plant Types**:
- After lichens, the next stage includes bryophytes (like mosses), which can thrive in both dry and moist conditions but do not constitute the climax community.

5. **Development of Shrubs and Trees**:
- As succession continues, larger plants such as shrubs and eventually trees establish themselves. These plants are more significant in size and contribute to the formation of a stable climax community.

6. **Conclusion**:
- Therefore, in xerarch succession, the climax community primarily consists of trees and shrubs, which are the final and stable forms of vegetation in such ecosystems.

### Final Answer:
The climax community in xerarch succession comprises mainly of **trees and shrubs**.
