Mycorrhiza is found in-

Options

A. Oligotrophic soil deficient in nutrients
B. Eutrophic soil rich in nutrients
C. Oligotrophic soil rich in humus
D. Eutrophic soil deficient in nutrients

Answer

**Step-by-Step Solution:**

1. **Understanding Mycorrhizae:** Mycorrhizae are a type of fungi that form a symbiotic relationship with the roots of plants. This association is beneficial for both the fungi and the plants.

2. **Function of Mycorrhizae:** The primary functions of mycorrhizae include enhancing nutrient absorption for plants, particularly phosphorus, and improving soil fertility. They also help in maintaining the pH of the soil.

3. **Habitat of Mycorrhizae:** Mycorrhizae are typically found in oligotrophic soils. These soils are characterized by a low nutrient content, which makes the symbiotic relationship with mycorrhizae crucial for plant survival and growth.

4. **Importance of Oligotrophic Soil:** In oligotrophic soils, the lack of nutrients means that plants often struggle to obtain the necessary resources for growth. Mycorrhizae help to bridge this gap by increasing nutrient availability, particularly phosphorus.

5. **Conclusion:** Therefore, mycorrhizae are predominantly found in oligotrophic soils, which are deficient in nutrients.

**Final Answer:** Mycorrhizae are found in oligotrophic soil.
