5.1.4 Describe what is meant by a food chain, giving three examples, each with at least three linkages (four organisms). A food chain shows the direction of energy flow from one species to another. For example, an arrow from A to B means that A is being eaten by B and therefore ind...
standing biomass and relatively low harvest of primary production by herbivores, the detrital food chain is dominant (Smith & Smith 2009). In deep-water aquatic ecosystems, with their low standing biomass, rapid turnover of organisms, and high rate of harvest, the grazing food chain may be ...
Thus, the four metals have a high potential of being biomagnified in the intertidal rocky shore food chain. MeHg possessed the highest and Hg(II) and Cd the lowest potential of trophic transfer among the four metals considered. Introduction Over the past decades, there has been substantial ...
