Introduction to Ecosystem Structure and Composition

The video tutorial introduces the concept of ecosystems, explaining the interdependence of living (biotic) and non-living (abiotic) components. It details the classification of biotic components into producers (autotrophs) and consumers (heterotrophs), further dividing consumers into herbivores, carnivores, and decomposers. Abiotic components such as rain, wind, and soil are also discussed, providing a comprehensive overview of ecosystem structure and composition.
