Mycorrhiza is an example of

Options

A. Symbiotic relationship
B. Ectoparasitism
C. Endoparasitism
D. Decomposers

Answer

**Step-by-Step Solution:**

1. **Understanding Mycorrhiza**: Mycorrhiza refers to the symbiotic association between fungi and the roots of higher plants. This relationship is crucial for the growth and health of many plants.

2. **Identifying the Nature of the Relationship**: In this association, both the fungi and the plant benefit from each other. The fungi help the plant absorb essential nutrients from the soil, such as phosphorus and nitrogen, while the plant provides carbohydrates produced through photosynthesis to the fungi.

3. **Evaluating the Options**:
- **Symbiotic Relationship**: This option indicates a mutually beneficial interaction, which is true for mycorrhiza.
- **Ectoparasitism**: This refers to a relationship where one organism benefits at the expense of another, which does not apply to mycorrhiza.
- **Endoparasitism**: Similar to ectoparasitism, this involves one organism living inside another and harming it, which is not the case here.
- **Decomposers**: This term refers to organisms that break down dead organic material, which is not related to mycorrhiza.

4. **Conclusion**: Since mycorrhiza represents a mutually beneficial relationship between fungi and plants, the correct answer is that mycorrhiza is an example of a **symbiotic relationship**.
