File Name: food chain and food web in ecosystem .zip
Food chains and food webs are easy to get confused since they both show the movement of energy through an ecosystem.
A food web or food cycle is the natural interconnection of food chains and a graphical representation usually an image of what-eats-what in an ecological community. Another name for food web is consumer-resource system. Ecologists can broadly lump all life forms into one of two categories called trophic levels : 1 the autotrophs , and 2 the heterotrophs. To maintain their bodies, grow, develop, and to reproduce , autotrophs produce organic matter from inorganic substances, including both minerals and gases such as carbon dioxide.
Green plants make their own food. They use the energy from the sun to make their own food. Some of this food is used, and some is stored in the roots, stems, and leaves. All living things need food to give them the energy to grow and move. A food chain shows how each living thing gets its food.
It shows who is eating who. The arrow means "is eaten by". Grass is eaten by Grasshopper is eaten by Toad is eaten by Snake is eaten by Hawk.

See photos Carnivore - an animal that eats other animals. See photos Omnivore - an animal that eats both plants and animals eg bears and humans.
See photos. Producer - usually a green plant that produces its own food by photosynthesis Primary Consumer - Animals that consume only plant matter. They are herbivores - eg rabbits, caterpillars, cows, sheep, and deer. Secondary Consumer - Animals that eat primary consumers herbivores.
Tertiary Consumer - Animals that eat secondary consumers ie carnivores that feed on other carnivores. Predators - kill for food. They are either secondary or tertiary consumers - eg polar bears, golden eagles Prey - are the organisms that predators feed on.
Examples of predator and prey species are: fox and rabbit; blue tit and caterpillar; wolf and lamb. Scavenger - a consumer that eats dead animals e. Detritivore - a consumer that obtains its nutrients from detritus Decomposer - an organism such as bacteria and fungi that breaks down dead organisms and their wastes. They do not 'eat' the food like scavengers, as they have no mouth-parts. Instead they break down solid matter into liquids which they can absorb.
Examples: bacteria and some fungi. See photos Trophic Level - A trophic level is each level in a food chain. Matter is always 'lost' as heat energy at each trophic level. Basal Energy Requirement B. Food Web - a network of interrelated food chains in a given area. Food Chain as an Example of a System A model of a food chain and the movement of energy.
