THE ECOSYSTEM Science and Health 5 What is an ECOSYSTEM? The ecosystem is the structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. An ecosystem is a chain of interactions between organisms and their environment. STRUCTURE OF THE ECOSYSTEM? The structure of an ecosystem is characterised by the organisation of both biotic and abiotic components. This includes the distribution of energy in our environment. It also includes the climatic conditions prevailing in that particular environment.
