TROPHIC LEVEL - the community of organisms that are grouped by type of food. The idea of T.L. allows you to understand the dynamics of energy flow and determines its traffic. structure. Autotrophic organisms (mostly. green plants occupy the first T.L. - (producers), herbivorous animals, the second (the first order consumers), predators that feed on herbivorous animals, the third (second order consumers), secondary predators the fourth (third order consumers). Organisms different traffic. circuits, but receiving food through the same number of links in traffic. circuit are on the same T.L. So, feed on leaves of alfalfa and cow beetle weevil kinds of Seaton are the consumers of the first order. The real relationship between T.L.. the community is very difficult.
