First of all there is mistake in the question. The name will be A.G. Tansley instead of A.G. Tausley.
According to A. G. Tansley, organisms cannot be separated as an entity from their environment or habitat. The ecosystems are referred to as basic units of nature. He considered organisms as well as inorganic constituents as parts of ecosystem and there is interchange of organic and inorganic matter between ecosystems. He considered living as well organic and inorganic matters of biome as part of ecosystem and ecosystem as a 'recognizable self-contained entity'.
E.P Odum considered ecosystem as basic functional unit of ecology. He recognized two functional components: autotrophic and heterotrophic and four constituents : abiotic, producers, consumers and decomposers. He emphasized on obligatory relationships, interdependence and causal relationships.
