_____ are important, decomposers that cause decay and decomposition of dead bodies of plants and animals.

Options

A. Saprophytic bacteria
B. Saprotrophic fungi
C. Plants, like Sarracenia
D. Both (a) and (b)

Explanation

To answer the question, "_____ are important decomposers that cause decay and decomposition of dead bodies of plants and animals," we need to identify the correct term that fits in the blank.

### Step-by-Step Solution:

1. **Understanding Decomposition**:
- Decomposition is a vital ecological process where complex organic materials are broken down into simpler inorganic substances. This process is essential for nutrient cycling in ecosystems.

2. **Identifying Decomposers**:
- Decomposers are organisms that break down dead organic matter. They convert dead plants and animals into simpler substances, which can then be reused by other organisms in the ecosystem.

3. **Types of Decomposers**:
- The main types of decomposers include:
- **Saprophytic Bacteria**: These bacteria feed on dead organic matter and play a crucial role in decomposition.
- **Saprotrophic Fungi**: These fungi also feed on dead organic matter and help in breaking it down.

4. **Analyzing the Options**:
- **Option A: Saprophytic Bacteria** - Correct, as they are decomposers.
- **Option B: Saprotrophic Fungi** - Correct, as they are also decomposers.
- **Option C: Plant like Sarsenia** - Incorrect, as Sarsenia (a carnivorous plant) does not function as a decomposer.
- **Option D: Both A and B** - Correct, since both saprophytic bacteria and saprotrophic fungi are important decomposers.

5. **Conclusion**:
- The correct answer is **Option D: Both A and B**. This means that both saprophytic bacteria and saprotrophic fungi are important decomposers that cause decay and decomposition of dead bodies of plants and animals.

### Final Answer:
**Both A and B (saprophytic bacteria and saprotrophic fungi) are important decomposers that cause decay and decomposition of dead bodies of plants and animals.**
