The term for communities and their interactions with their environment is referred to as an ecosystem. Ecosystems encompass both biotic (living) and abiotic (non-living) components, allowing for complex interactions and energy flow. These systems can vary in size and complexity, ranging from small ponds to vast forests. Understanding ecosystems is essential for grasping ecological principles, biodiversity, and the interdependence of organisms. By studying ecosystems, scientists can assess biodiversity, monitor environmental changes, and develop strategies for conservation and sustainable resource management, promoting ecological health and resilience.
