Ecosystems are dynamic systems characterized by interactions among living organisms and between them and the physical environment. Energy flows unidirectionally through producers, consumers, and decomposers while nutrients cycle through various biogeochemical processes. Understanding energy flow, trophic levels, food chains, and the impact of human activities is essential for promoting ecosystem stability and conservation.
