Charles Elton subsequently pioneered the concept of food cycles, food chains, and food size in his classical 1927 book "Animal Ecology"; Elton's 'food cycle' was replaced by 'food web' in a subsequent ecological text. [96] After Charles Elton's use of food webs in his 1927 synthesis, [97] they became a central concept in the field of ecology.

Map of Labrador Current. The Labrador Current is a cold current in the North Atlantic Ocean which flows from the Arctic Ocean south along the coast of Labrador and passes around Newfoundland, continuing south along the east coast of Canada near Nova Scotia. Near Nova Scotia, this cold water current meets the warm northward moving Gulf Stream.
A food web model is a network of food chains. Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.
Not to be confused with its close relatives, the grass pickerel and the chain pickerel, this fish is unique in the fact that it has brightly colored red fins. [2] Like all pikes, the redfin pickerel is an ambush predator , lying amongst thick vegetation in wait for smaller, more agile prey to enter within its range of attack.
