Study Notes
Characteristics of Ecosystems
- Energy and matter flow between living organisms and their environment, creating a continuous exchange essential for ecosystem health.
- Dynamism: Ecosystems are characterized by the movement of energy and matter through food chains and networks, leading to constant changes and interactions among species.
- Variability: Ecosystem composition is not fixed; it can change in response to fluctuations in environmental conditions, impacting the community structure.
- Complexity: Adaptation and evolution of organisms occur in response to changing environments, contributing to the intricate nature of ecosystems.
- All components within an ecosystem must maintain a balance for proper functioning; this balance is vulnerable to disruption from natural phenomena or human activities.
