En näringskedja börjar med växter (eller blågröna bakterier). Det är ju växterna som tillverkar (producerar) energirik näring med hjälp av solenergi. Man säger att växterna är ekosystemets producenter. Djuren äter (konsumerar) näringen och kallas konsumenter.

Djur som äter växter kommer först bland konsumenterna i en näringskedja och kallas förstahandskonsumenter. Därefter följer olika rovdjur som är andrahandskonsumenter, tredjehandskonsumenter osv. De rovdjur som kommer sist i en näringskedja kallas även toppkonsumenter.

Nedan visas en näringskedja från en trädgård som ju också kan beskrivas som ett ekosystem. Ett plommonträd är näringskedjans producent. Den producerade näringen konsumeras i tur och ordning av amiralfjäril, koltrast och sparvhök.Näringsväv

Ovan visas fler av trädgårdens invånare än de som finns på föregående sida. I bilden kan du hitta näringskedjan som innehåller plommonträd, amiralfjäril, koltrast och sparvhök (röda pilar). Du kan också följa näringens väg genom många fler näringskedjor, t.ex. plommonträd, plommonbladlus, nyckelpigans larv och skogsödla. Det framgår att ekosystemets många näringskedjor är sammanvävda med varandra. Tillsammans bildar de en näringsväv.

Många arter kan förekomma på olika nivåer i olika näringskedjor. Bland annat koltrasten kan vara både växtätare (när den äter t.ex. plommon) och rovdjur (när den äter t.ex. larver). Det visar hur invecklade samspelen är i ett ekosystem.

A food chain begin with plants (or blue-green bacteria). It's the plants that manufacture (produce) energetic nourishment using solar energy. They say that the plants are the ecosystem's producers. Animals eat (consuming) sector and are called consumers.Animals that eat plants comes first among consumers in a food chain and is called förstahandskonsumenter. This is followed by various predators that are andrahandskonsumenter, tredjehandskonsumenter etc. The predators that will last in a food chain is also called top consumers.Below is a food chain from a garden that also can be described as an ecosystem. A plum tree is food chain. The produced nutrients consumed in turn by Admiral, Blackbird, and sparrowhawk. Food WebThis is more of the garden's inhabitants than those found on the previous page. In the picture you can find the food chain that contains the plum trees, Admiral, Blackbird and sparrowhawks (red arrows). You can also follow its way through many more food chains, for example. plum tree, plommonbladlus, ladybug larva and forest lizard. It is apparent that many of the ecosystem food chains are interwoven with each other. Together they form a food Web.Many species can occur at various levels in various food chains. Among other things, the Blackbird can be both herbivores (when it eats e.g. plum) and predator (when it eats e.g. larvae). It shows how complex interactions are in an ecosystem.

A food chain starts with plants (or blue-green bacteria). It's the plants that manufacture (produce) energy rich nutrients using solar energy. They say that the plants are ecosystem producers. The animals eat (consume) the industry and consumers called.

Animals that eat plants come first among the consumers in a food chain and are called primary consumers. Then follow different predators that are secondary consumers, thirdly, consumers etc. The predators that will last in the food chain is also called the top consumers.

Below is a food chain from a garden which also can be described as an ecosystem. A plum tree's food chain producer. The industry produced is consumed in turn by Admiral butterfly, blackbird and sparvhök.Näringsväv

Above is more of the garden's inhabitants than those on the previous page. In the picture you can find the food chain that includes plum trees, admiral butterfly, blackbird and sparrow hawks (red arrows). You can also follow the industry's way through many more food chains, such as plum trees, plommonbladlus, nyckelpigans caterpillar and forest lizard. According to the ecosystem many food chains are intertwined. Together they form a food web.

Many species can occur at different levels in different food chains. Among other things, the blackbird can be both herbivores (eg when eating plum) and predators (eg when eating caterpillars). It shows how complex interactions in an ecosystem.
