Ecological Pyramid
The Ecological Pyramid (pronunciation: /iːkəˈlɒdʒɪkəl ˈpɪrəmɪd/), also known as the Energy Pyramid, is a graphical representation that illustrates the flow of energy through different levels of a food chain. The concept of the Ecological Pyramid was first introduced by Charles Elton, a British ecologist, in 1927.
Etymology
The term "Ecological Pyramid" is derived from the Greek word "oikos" meaning "house" or "environment", and the Latin word "pyramis" meaning "a pyramid". It refers to the hierarchical structure of energy flow in an ecosystem.
