Choose the correct answer :
The minimum number of components required for an ecosystem to survive are :

Options

A. Producers & decomposers
B. Producers & primary consumers
C. Producers & secondary consumers
D. Primary consumers & decomposers

Answer

To determine the minimum number of components required for an ecosystem to survive, we can break down the components as follows:

1. **Identify the essential components of an ecosystem**:
- An ecosystem consists of various components, but the minimum essential components are:
- **Autotrophs**: These are organisms that can produce their own food, typically through photosynthesis (e.g., plants).
- **Decomposers**: These organisms break down dead organic matter and recycle nutrients back into the ecosystem (e.g., fungi, bacteria).

2. **Understanding the roles of these components**:
- Autotrophs are crucial because they form the base of the food chain, providing energy for other organisms.
- Decomposers are equally important as they help in nutrient cycling, ensuring that essential nutrients are available for autotrophs to use.

3. **Examine the question for minimum components**:
- The question specifically asks for the minimum number of components. This means we are looking for the least number of different types of organisms necessary for the ecosystem to function.

4. **Conclusion**:
- Therefore, the minimum number of components required for an ecosystem to survive is **two**: Autotrophs and Decomposers.

The correct answer is **Option A: Autotrophs and Decomposers**.
