The correct Answer is:
To answer the question regarding the habitats of members of phycomycetes, we can analyze each option step by step. ### Step-by-Step Solution: 1. **Understanding Phycomycetes**: - Phycomycetes, also known as lower fungi, include organisms that are often found in moist environments. They are characterized by their simple structure and reproductive methods. 2. **Analyzing Option (i): Aquatic habitats**: - Many members of phycomycetes are indeed found in aquatic habitats. They thrive in water bodies where they can reproduce via zoospores, which require water for movement. 3. **Analyzing Option (ii): On decaying wood**: - Phycomycetes are saprophytic fungi, meaning they obtain nutrients from decaying organic matter, including decaying wood. This is a common habitat for them. 4. **Analyzing Option (iii): Moist and damp places**: - Phycomycetes prefer moist and damp environments for growth and reproduction. This is essential for their life cycle, particularly for the movement of their reproductive cells. 5. **Analyzing Option (iv): As obligate parasites on plants**: - Some members of phycomycetes are obligate parasites, meaning they can only grow on living hosts. For example, *Phytophthora infestans* causes late blight in potatoes, and *Peronospora viticola* causes downy mildew in grapes. ### Conclusion: Based on the analysis: - Options (i), (ii), (iii), and (iv) are all correct in describing the habitats of phycomycetes. However, if we have to choose from the given options, we can conclude that members of phycomycetes are found in aquatic habitats, on decaying wood, in moist and damp places, and as obligate parasites on plants. ### Final Answer: All options (i), (ii), (iii), and (iv) are correct regarding the habitats of phycomycetes.
To answer the question regarding the habitats of members of phycomycetes, we can analyze each option step by step. ### Step-by-Step Solution: 1. **Understanding Phycomycetes**: - Phycomycetes, also known as lower fungi, include organisms that are often found in moist environments.
