An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in an ecosystem. A pyramid of energy shows how much energy is retained in the form of new biomass from each trophic level, while a pyramid ...
The linkages in a food web illustrate the feeding pathways, such as where heterotrophs obtain organic matter by feeding on autotrophs and other heterotrophs. The food web is a simplified illustration of the various methods of feeding that link an ecosystem into a unified system of exchange.
The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way ...
A food pyramid and a corresponding food web, demonstrating some of the simpler patterns in a food web A graphic representation of energy transfer between trophic layers in an ecosystem. Energy flow is the flow of energy through living things within an ecosystem. [1]
The relationship between ecosystem complexity and stability is a major topic of interest in ecology.Use of ecological networks makes it possible to analyze the effects of the network properties described above on the stability of an ecosystem.
An interaction web, shown above right, [9] is similar to a topological web, but instead of showing the movement of energy or materials, the arrows show how one group influences another. In interaction food web models, every link has two direct effects, one of the resource on the consumer and one of the consumer on the resource. [10]
