Mycorrhiza is found in

Options

A. oligotrophic soil
B. eutrophic soil
C. both (1) and (2)
D. none

Answer

**Step-by-Step Solution:**

1. **Understanding Mycorrhiza**: Mycorrhiza refers to a symbiotic relationship between fungi and plant roots. This association is beneficial for both organisms, as the fungi help the plants absorb water and essential nutrients from the soil, while the plants provide carbohydrates to the fungi.

2. **Types of Soil**: There are two types of soil mentioned in the question:
- **Oligotrophic Soil**: This type of soil is characterized by low nutrient content, particularly low levels of nitrogen and phosphorus.
- **Eutrophic Soil**: In contrast, eutrophic soil is rich in nutrients and supports a high level of biological productivity.

3. **Role of Mycorrhiza in Soil**: Mycorrhizae play a crucial role in nutrient acquisition, especially in nutrient-poor environments like oligotrophic soils. They enhance the plant's ability to absorb phosphorus and other essential nutrients, which are often limited in such soils.

4. **Conclusion**: Given that mycorrhizae are particularly beneficial in nutrient-poor conditions, they are most commonly found in oligotrophic soil rather than eutrophic soil.

5. **Final Answer**: Mycorrhiza is found in oligotrophic soil.
