Ecological efficiency in the marine environment

Secondary production at sea tends to be more efficient as well, with up to a 15% transfer efficiency between trophic levels. Some of this difference can be explained by the lower energy requirements marine organisms have compared to their terrestrial counterparts. Most marine animals are cold blooded and expend little energy on temperature regulation. Furthermore, locomotion is more efficient in the marine environment; marine organisms reap the benefits of living in a buoyant liquid, spend much less effort countering gravity, and can drift and swim, instead of walk or fly. Marine animals also reproduce en masse and expend little energy caring for their young.
