Ecosystem Stability refers

• The ability of a community or ecosystem to maintain its structure and function over time.

• The ability of a community or ecosystem to quickly adapt to changes.

• The variety and abundance of species within an ecosystem.

• The rate at which species evolve within the ecosystem.

Complex interactions, such as predator-prey relationships, competition, and symbiosis, help maintain ecosystem stability

• They regulate species population and resource distribution, preventing any one species from dominating the ecosystem.

• They lead to increased competition that destabilizes ecosystems.

• They have minimal effects on the balance of ecosystems.

• They reduce biodiversity, thereby weakening ecosystem resilience.
