Ecologists look at how organisms interact with the environment and each other, and they study the complex and interconnected systems which influence life on Earth. (See community ecology: Trophic pyramids and the flow of energy; biosphere: The flow of energy and nutrient cycling.). Individual species are related to various adaptations like physiological adaptation, morphological adaptation, and behavioural adaptation. -Ecology is the scientific study of interactions among organisms and between organisms and their physical environment. A system of such relationships within a particular environment. In 1942 Raymond L. Lindeman of the United States developed the trophic-dynamic concept of ecology, which details the flow of energy through the ecosystem. https://www.britannica.com/science/ecology.

The study of both energy flow and nutrient cycling was stimulated by the development of new materials and techniques—radioisotope tracers, microcalorimetry, computer science, and applied mathematics—that enabled ecologists to label, track, and measure the movement of particular nutrients and energy through ecosystems. Ecology is defined as the study of ecosystems. [2]These models are then tested in the laboratory and thefield. The term “ecology” was coined by the German zoologist,Ernst Haeckel, in 1866 to describe the “economies” ofliving forms.
