Ecosystem is a functional unit of nature where living organisms (biotic components) such as plants, animals, and microorganisms interact with the non-living components (abiotic components) like air, water, soil, light, and temperature. In an ecosystem, energy flows unidirectionally from the sun to producers and then to consumers, while nutrients are recycled through biogeochemical cycles. Producers capture solar energy, consumers transfer energy through food chains and food webs, and decomposers break down organic matter, returning nutrients to the soil. Ecosystems can be natural (forest, pond, desert, grassland) or artificial (crop field, aquarium). Each ecosystem maintains ecological balance through interactions among its components and supports life on Earth.
