If there are 25 African elephants (primary consumer) living together in a given area, with an average weight of 4,000 kg each, approximately how much biomass of plant material would hypothetically be necessary as a harvestable food supply to support all of them on an ongoing basis? (Assume a 10% efficiency in energy transfer.)

Given the 10% efficiency in energy transfer, to support 25 elephants each weighing 4,000 kg (totaling 100,000 kg of biomass), you would need 10 times that amount in plant biomass, which is 1,000,000 kg.
