Lead author Diego Barneche is an adjunct member of the LIT Oceans Institute and has recently joined the Australian Institute of Marine Science. The research team measured the transfer of energy from single-celled algae (phytoplankton) to small animals that eat them (zooplankton) over seven years in an artificially warmed pond. The results suggest that 4┬░C of warming - a scenario that is on track with current predictions for temperature rises by the end of the century - reduced energy transfer in the plankton food webs by up to 56%. In general, about 10% of energy produced on one level of a food web makes it up to the next level. This happens because organisms expend a lot of energy on a variety of functions over a lifeti
