WebFood chains and webs show the transfer of energy between trophic levels. They can be represented as pyramids of number and biomass and the efficiency of these transfers can be calculated. Part of In agricultural environments, maximizing energy transfer from producer (food) to consumer (livestock) can yield economic benefits. A sub-field of agricultural science has emerged that explores methods of monitoring and improving ecological and related efficiencies. In comparing the net efficiency of energy utilization by cattle, breeds historically kept for beef production, such as the Hereford, outperformed those kept for dairy production, such as the Hols…
