Ecological efficiency
Ecological Efficiency
Ecological efficiency (pronounced: /ˌiːkəˈlɒdʒɪkəl ɪˈfɪʃənsi/) is a term used in Ecology to describe the efficiency with which energy is transferred from one trophic level to the next. It is determined by a combination of efficiencies relating to organismic resource acquisition and assimilation in an ecosystem.
Etymology
The term "ecological efficiency" is derived from the Greek word "oikos" meaning "household", "logos" meaning "study of", and the Latin word "efficiens" meaning "accomplishing, producing, effecting". Together, they refer to the study of how effectively energy is produced and transferred in an ecosystem.
