Explain how ecosystems exist at a range of scales.

Ecosystems can be found at various scales, from small local environments like ponds or forests to vast global systems such as oceans and biomes. Each ecosystem is characterized by its unique interactions among living organisms (biotic components) and their physical surroundings (abiotic components). These interactions shape the structure and function of the ecosystem, influencing biodiversity and the flow of energy and nutrients. Understanding ecosystems at different scales helps us appreciate their complexity and the importance of conserving them for ecological balance and human well-being.
