Many microorganisms are decomposers. They decompose all dead plants and animals and return matter back into the environment. Microorganisms are a important part of the

Options

A. carbon cycle
B. nitrogen cycle
C. sulfur cycle
D. iron cycle

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of Microorganisms**: Microorganisms play a crucial role in the ecosystem, particularly as decomposers. They break down dead organic matter, such as dead plants and animals.

2. **Decomposition Process**: When microorganisms decompose dead organisms, they convert complex organic materials into simpler substances. This process releases nutrients back into the soil and environment, making them available for other living organisms.

3. **Nutrient Cycling**: The nutrients released during decomposition are essential for the growth of plants. This process is a part of nutrient cycles, such as the carbon cycle and nitrogen cycle, which are vital for maintaining ecological balance.

4. **Importance of Decomposers**: Decomposers, including various microorganisms, are essential for recycling nutrients in the ecosystem. They help in maintaining soil fertility and contribute to the overall health of the environment.

5. **Final Statement**: Therefore, microorganisms are an important part of the **ecosystem**. They ensure that matter is recycled and that nutrients are returned to the environment, supporting life.
