Biological equilibrium is an equilibrium among the

Options

A. Decomposers and producers only
B. Producers and consumers only
C. Producers, consumers and decomposers
D. Producers only

Answer

**Step-by-Step Solution:**

1. **Understanding Biological Equilibrium**: Biological equilibrium refers to a state of balance within an ecosystem where various biological components interact with each other in a stable manner.

2. **Identifying the Components**: The main components of an ecosystem include:
- **Producers**: These are organisms that can produce their own food, typically through photosynthesis. They form the base of the food chain.
- **Consumers**: These are organisms that consume producers or other consumers for energy. They can be herbivores, carnivores, or omnivores.
- **Decomposers**: These organisms break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle.

3. **Analyzing the Options**:
- **Option A**: Decomposers and producers only – This does not include consumers, which are crucial for the balance.
- **Option B**: Producers and consumers only – This excludes decomposers, which play a vital role in recycling nutrients.
- **Option C**: Producers, consumers, and decomposers – This option includes all three components, which are essential for a stable ecosystem.
- **Option D**: Producers only – This ignores the roles of consumers and decomposers.

4. **Conclusion**: The correct answer is **Option C**: Producers, consumers, and decomposers. This combination creates a dynamic balance that is necessary for maintaining biological equilibrium in an ecosystem.
