Compare energy transfer in a food chain to energy transfer in a food web
Ket [755]
Energy flows up a food chain, from the primary producers to the primary consumers, to the secondary consumers, up to the tertiary and then quaternary consumers. Energy flows when one organism eats another lower in the food chain, the energy is transferred by heat and movement, some though is lost. They eat each other but it only gets half the energy stored.
