The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Homeostasis**: The term "homeostasis" refers to the ability of an organism or a system to maintain a stable internal environment despite external changes. In the context of ecosystems, it describes how different components interact to maintain balance. 2. **Equilibrium in Ecosystems**: In an ecosystem, homeostasis is achieved when various biotic (living) and abiotic (non-living) factors are in balance. This equilibrium allows the ecosystem to function effectively and sustain life. 3. **Regulators vs. Conformers**: - **Regulators**: These are organisms that can maintain their internal environment regardless of external conditions. For example, birds and mammals can regulate their body temperature. - **Conformers**: These organisms cannot regulate their internal environment and instead conform to the external conditions. Most invertebrates fall into this category. 4. **Examples of Homeostasis**: - In humans, homeostasis is demonstrated through mechanisms like shivering in cold temperatures to generate heat and sweating in hot temperatures to cool down. - In ecosystems, homeostasis can be seen in the balance of predator-prey relationships, nutrient cycling, and energy flow. 5. **Conclusion**: Therefore, in an ecosystem, homeostasis refers to a state of equilibrium where various factors are balanced, allowing for the sustainability of the ecosystem. **Final Answer**: Homeostasis in an ecosystem refers to a state of equilibrium. ---
