These organisms have an ability to help in recycling of nutrients. Which organisms are these?

Options

A. Bacteria
B. Diatoms
C. Viruses
D. Algae

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which organisms have the ability to help in recycling nutrients. This implies we need to identify organisms that contribute to the breakdown of organic matter.

2. **Identifying Key Organisms**: The options given are bacteria, diatoms, viruses, and algae. We need to evaluate which of these organisms are involved in nutrient recycling.

3. **Role of Decomposers**: Decomposers are organisms that break down dead organic material, returning nutrients to the soil. This process is essential for nutrient cycling in ecosystems.

4. **Evaluating Each Option**:
- **Bacteria**: These are microorganisms that play a crucial role in decomposition. They break down complex organic matter into simpler substances, thus recycling nutrients.
- **Diatoms**: These are photosynthetic organisms and do not primarily function as decomposers.
- **Viruses**: These are infectious agents and do not contribute to nutrient recycling.
- **Algae**: Like diatoms, they are mainly photosynthetic and do not play a significant role in decomposition.

5. **Conclusion**: The organisms that help in recycling nutrients are primarily **bacteria** and **fungi**, as they are the main decomposers in ecosystems.

**Final Answer**: Bacteria (and fungi) are the organisms that help in recycling nutrients.
