Plants growing in nutrient poor soils that are not very condusive to microflora often become

Options

A. insectivaorous
B. saprotrophic
C. chemotrophic
D. xerophytes

Answer

To answer the question about what plants growing in nutrient-poor soils that are not very conducive to microflora often become, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Problem**:
- The question states that we are dealing with plants that are growing in nutrient-poor soils. This means that these plants are not receiving the necessary nutrients from the soil for their growth and development.

2. **Understand Nutrient Acquisition**:
- Plants typically absorb nutrients from the soil through their roots. However, in nutrient-poor soils, this process is not effective, and plants must find alternative ways to obtain nutrients.

3. **Consider Alternative Nutrient Sources**:
- To survive in such conditions, some plants adapt by developing unique mechanisms to acquire nutrients. One common adaptation is to become insectivorous.

4. **Define Insectivorous Plants**:
- Insectivorous plants are those that derive some or most of their nutrients by trapping and consuming insects. This adaptation allows them to supplement their nutrient intake from the poor soil.

5. **Provide Examples**:
- Examples of insectivorous plants include the Venus flytrap and the Nepenthes (pitcher plant). These plants have specialized structures that help them capture and digest insects.

6. **Differentiate from Other Types**:
- While saprotrophic plants derive nutrients from dead and decaying matter, and chemotrophic organisms use chemical energy, these are not the adaptations primarily seen in plants growing in nutrient-poor soils. Xerophytes are adapted to dry conditions, which is not the focus of this question.

7. **Conclusion**:
- Therefore, the correct answer to the question is that plants growing in nutrient-poor soils that are not conducive to microflora often become insectivorous.

### Final Answer:
Plants growing in nutrient-poor soils that are not very conducive to microflora often become insectivorous.
