Plant decomposers are under these kingdoms

Options

A. Fungi and plantae
B. Monera and fungi
C. Protists and Monera
D. Protista and Plantae

Answer

**Step-by-Step Solution:**

1. **Understanding Decomposers**: Decomposers are organisms that obtain their energy from dead organic matter, which includes both dead plants and animals. They play a crucial role in ecosystems by breaking down dead material and recycling nutrients.

2. **Identifying Plant Decomposers**: Since the question specifically asks about plant decomposers, we need to focus on organisms that derive their energy from dead plant material.

3. **Types of Decomposers**: The main groups of decomposers include fungi and certain bacteria. Fungi are well-known for their ability to decompose organic material, including dead plants. Bacteria also play a significant role in decomposition.

4. **Analyzing Options**:
- **Option 1: Fungi and Plants**: While fungi are decomposers, plants are not decomposers; they are producers. Therefore, this option is incorrect.
- **Option 2: Monera and Fungi**: Monera (which includes bacteria) can be heterotrophic and obtain energy from dead organic matter. Fungi are also heterotrophic and decompose dead plants. This option is correct.
- **Option 3: Fungi and Bacteria**: This option is also correct because both fungi and bacteria are decomposers that feed on dead organic matter.
- **Option 4: Protists and Monerans**: Protists do not primarily function as decomposers, while some monerans (bacteria) can be. This option is partially correct but not the best choice.

5. **Conclusion**: The best answer to the question "Plant decomposers are under these kingdoms" is **Option 2: Monera and Fungi** because both groups include organisms that decompose dead plant material.
