Environment Marathon lecture notes explain ecology and the environment through key concepts such as ecology as the study of interactions among organisms and between organisms and their abiotic environment. The material defines ecosystem as the structural and functional unit of ecology, listing abiotic components (air, water, soil, suspended particulates) and biotic components (plants, animals, micro-organisms). It also outlines types of ecosystems, including natural terrestrial and aquatic systems and man-made systems, and highlights essential ecosystem components like producers, consumers, and decomposers across carbon, water, air, and nutrient cycles.
