Osmotrophs belong to

Options

A. primary consumers
B. secondary consumer
C. top carnivores
D. decomposers

Explanation

**Step-by-Step Solution:**

1. **Understanding the Term "Osmotrophs":**
- Osmotrophs are organisms that obtain their nutrients by absorbing dissolved organic substances from their environment.

2. **Identifying the Type of Organism:**
- Osmotrophs are classified as heterotrophs, meaning they cannot produce their own food and rely on other organisms for nutrition.

3. **Examples of Osmotrophs:**
- The primary examples of osmotrophs are bacteria and fungi. These organisms play a crucial role in ecosystems by breaking down organic matter.

4. **Nutrient Uptake Mechanism:**
- Osmotrophs absorb nutrients through the active uptake of soluble materials across their cell membranes, which is a characteristic feature of decomposers.

5. **Classification in the Food Chain:**
- In the context of the food chain, osmotrophs (bacteria and fungi) are classified as decomposers because they break down dead organic matter and recycle nutrients back into the ecosystem.

6. **Conclusion:**
- Based on the above information, osmotrophs belong to the category of decomposers.

**Final Answer:**
Osmotrophs belong to the category of decomposers.
