Food Chain And Food Webs Explained Here, the producers are consumed by the predators primary and secondary consumers and then the detritivores and finally by decomposers. when many such individual food chains occur in an ecosystem, it is known as food web. a food chain shows a direct transfer of energy between organisms. as every organism can feed on multiple things, a food web. A food web is a graphic representation of a holistic, nonlinear web of primary producers, primary consumers, and higher level consumers used to describe ecosystem structure and dynamics (figure 1). figure 1. example of simplified food chains (a) and food webs (b) of terrestrial and marine ecosystems. developed by ladyofhats and licensed under cc0.
What Is A Food Chain Bbc Bitesize Producers (autotrophs): at the base of the food web are the primary producers, such as plants, algae, and some bacteria. these organisms produce their food through photosynthesis or chemosynthesis and form the foundation of the food web by converting energy from the sun into organic matter. primary consumers (herbivores): these are organisms. A million to one marine food webs are usually longer than terrestrial food webs. scientists estimate that if there are a million producers (algae, phytoplankton, and sea grass) in a food web, there may only be 10,000 herbivores. such a food web may support 100 secondary consumers, such as tuna. Food chains. a food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher level consumers, and finally decomposers. these levels are used to describe ecosystem structure and dynamics. Food web interactions. although depictions of food webs often show direct single line paths of consumption from producers to consumers on various trophic levels like food chains do, they can also show the ways in which some organisms diverge from these patterns. for example, larger carnivores and omnivores whose diets are not limited to a few.

A food chain outlines who eats whom. a food web is all of the food chains in an ecosystem. each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. primary consumers, mostly herbivores, exist at the next level, and secondary and. Food web is an important ecological concept. basically, food web represents feeding relationships within a community (smith and smith 2009). it also implies the transfer of food energy from its.
