Energy flow (ecology)
Energy flow (ecology)
Energy flow (pronounced: /ˈɛnərdʒi floʊ/) in Ecology refers to the passage or transfer of energy through a system of organisms in an Ecosystem. The term originates from the Greek words "energeia" (activity, operation) and "rhein" (to flow).
Overview
In an ecosystem, energy flows from one trophic level to the next. The energy flow starts from the Sun, which is the ultimate source of energy. This energy is captured by Photosynthetic organisms, such as plants and algae, which convert solar energy into chemical energy in the form of glucose. This energy is then passed on to the next trophic level, the Herbivores, when they consume the plants. The energy continues to flow to Carnivores when they eat the herbivores, and so on.
