Answer

To solve the question regarding which sentences are correct, we will analyze each statement one by one based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Evaluate the First Statement:**
- The statement claims that the Mediterranean Orchid employs sexual deceit to get pollination done by species of bee.
- According to the transcript, this statement is correct. The Mediterranean Orchid mimics a female bee, attracting male bees for pseudo-copulation, which results in pollination.

2. **Evaluate the Second Statement:**
- The statement mentions a mycorrhizal association between fungi and roots of lower plants.
- The transcript indicates that this statement is incorrect. Mycorrhizal associations occur between fungi and the roots of higher plants, not lower plants.

3. **Evaluate the Third Statement:**
- The statement asserts that when resources are limited, growth is usually exponential.
- The transcript clarifies that this statement is incorrect. Exponential growth occurs when resources are unlimited, not limited.

4. **Evaluate the Fourth Statement:**
- The statement suggests that the competitive exclusion principle tells that two species can coexist.
- According to the transcript, this statement is also incorrect. The competitive exclusion principle indicates that two species competing for the same resources cannot coexist; one will outcompete the other.

5. **Conclusion:**
- Based on the evaluations:
- The first statement is correct.
- The second, third, and fourth statements are incorrect.
- Therefore, the correct answer to the question is that only the first statement is correct.

### Final Answer:
Only the first statement is correct.
