In other words, ecology can be defined as a field of study which deals with the relationship of living organisms with one another and with the environment in which they live. Producers: Producers are autotrophs (Green plants and some micro-organisms) which can manufacture their own food from simple inorganic materials during the process of photosynthesis and chemosynthesis. There is a unique interaction among the various components of an ecosystem. Nutrients, on the other hand, are recycled within an ecosystem, and their supply normally limits biological activity. Concept of an Ecosystem: The term ecosystem was coined in 1935 by the Oxford ecologist Arthur Tansley to encompass the interactions among biotic and abiotic components of the environment at a given site. Ecology includes the study … Biotic Components: The biotic components include the living things (plants and animals) which can be grouped into producers, consumers and decomposers. There are some important concepts commonly used in the study of ecology which enable one to understand the subject matter. Ecology and ecosystem are two closely related terms which describe the interactions of organisms with their environment. These are the biotic (living) components and the abiotic (non-living) components. Ecosystem Ecology looks at energy transformations and biogeochemical cycling within ecosystems.

ÉCOSYSTÈMES ET FLUX ÉNERGÉTIQUE. The living and non-living components of an ecosystem are known as biotic and abiotic components, respectively. 5. An ecosystem is a natural system that consists of a set of living organisms (biocoenosis) and the physical environment where related (biotope).
