State whether the following statement is true or false :
Mushroom is a decomposer.

Answer

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement we need to evaluate is "Mushroom is a decomposer."

2. **Defining Decomposers**: Decomposers are organisms that break down dead or decaying organic matter. They play a crucial role in the ecosystem by recycling nutrients back into the soil.

3. **Identifying Mushrooms**: Mushrooms are a type of fungus. They do not produce their own food like plants (which are autotrophs) but instead obtain nutrients by decomposing organic matter.

4. **Role of Mushrooms in the Ecosystem**: As mushrooms break down dead plants and animals, they help in the decomposition process, making them essential decomposers in the ecosystem.

5. **Conclusion**: Since mushrooms do indeed break down dead or decaying matter, the statement "Mushroom is a decomposer" is true.

**Final Answer**: True
