Fungi are ecologically important because :-

Options

A. They yield antibiotics
B. They are used in genetic studies
C. They function as decomposers
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the ecological importance of fungi. This means we need to focus on how fungi contribute to the environment and ecosystem.

2. **Identifying Fungi's Role**: Fungi are primarily known for their saprophytic mode of nutrition. This means they obtain their food by decomposing organic matter.

3. **Decomposers in the Ecosystem**: Fungi, along with bacteria, are considered major decomposers in the ecosystem. They play a crucial role in breaking down dead organic material, which is essential for nutrient cycling.

4. **Breaking Down Organic Matter**: The process of decomposition involves fungi breaking down complex organic substances into simpler, soluble forms. This process is vital as it makes nutrients available for plants.

5. **Nutrient Reabsorption by Plants**: The simple forms of nutrients released by fungi during decomposition can be reabsorbed by plants, thus supporting plant growth and maintaining the health of the ecosystem.

6. **Conclusion**: Therefore, the ecological importance of fungi lies in their role as decomposers, which helps in recycling nutrients in the ecosystem.

**Final Answer**: Fungi are ecologically important because they act as decomposers, breaking down organic matter and converting it into simpler, usable forms that can be reabsorbed by plants.
