Options

A. Bryophytes in general are of little economic importance
B. They reduce the impact of falling rain and prevent soil erosion
C. Some mosses provide food for herbaceous mammals, birds and other animals
D. Mosses along with lichens are the last organisms to colonize rocks

Answer

To determine which statement is not true for bryophytes, we will analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants that include mosses and liverworts. They are typically found in moist environments.

2. **Evaluating Statement 1**:
- "Bryophytes in general are of little economic importance."
- This statement is true. Bryophytes do not have significant economic uses compared to other plant groups.

3. **Evaluating Statement 2**:
- "They reduce the impact of falling rain and prevent soil erosion."
- This statement is also true. Mosses form dense mats that help absorb water and reduce soil erosion.

4. **Evaluating Statement 3**:
- "Some mosses provide food for herbaceous mammals, birds, and other animals."
- This statement is true as well. Certain mosses do serve as food for various animals, especially in colder regions.

5. **Evaluating Statement 4**:
- "Mosses, along with lichens, are the last organisms to colonize rock."
- This statement is not true. In fact, mosses and lichens are among the first organisms to colonize bare rock, playing a crucial role in ecological succession.

6. **Conclusion**:
- The statement that is not true for bryophytes is the fourth one regarding their role in colonizing rock.

### Final Answer:
The statement that is not true for bryophytes is: "Mosses, along with lichens, are the last organisms to colonize rock."
