Which must be preserved in ecosytem, if the sytem is to be maintained

Options

A. Producers and carnivores
B. Producers and decomposers
C. Carnivores and decomposers
D. Herbivores and carnivores

Answer

To answer the question about what must be preserved in an ecosystem for it to be maintained, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Key Components of an Ecosystem**:
- An ecosystem consists of various components, including producers (plants), herbivores (primary consumers), carnivores (secondary consumers), and decomposers (fungi and bacteria).

2. **Understand the Role of Producers**:
- Producers are essential as they are the primary source of energy in an ecosystem. They convert sunlight into food through photosynthesis, forming the base of the food chain.

3. **Recognize the Importance of Decomposers**:
- Decomposers play a crucial role in breaking down dead organic matter and recycling nutrients back into the soil. This process prevents the accumulation of waste and maintains soil fertility.

4. **Evaluate the Options Given**:
- The options provided include:
- Producers and carnivores
- Reducers and decomposers
- Carnivores and decomposers
- Herbivores and carnivores
- Among these, the most critical components for ecosystem maintenance are producers and decomposers.

5. **Conclude the Answer**:
- Therefore, to maintain an ecosystem, it is essential to preserve both producers and decomposers. Without producers, there would be no food source for herbivores and carnivores, and without decomposers, waste would accumulate, leading to environmental degradation.

### Final Answer:
**Producers and decomposers must be preserved in an ecosystem for it to be maintained.**
