energy pyramid
energy pyramid
Danh từ
Số nhiều: energy pyramids
This term is a specialized ecological concept used primarily in biological and environmental sciences. It serves as a visual tool to demonstrate the inefficiency of energy transfer between trophic levels, typically showing that only a small fraction of energy is passed from one level to the next.
In academic writing, it is often contrasted with biomass pyramids or pyramids of numbers. While a biomass pyramid can sometimes be inverted (such as in certain marine ecosystems), an energy pyramid is always upright because energy is lost as heat and cannot be recycled back to the producers.
