  2. 2. A food chain shows how each living thing gets food, and how nutrientsand energy are passed from creature to creature. Food chains beginwith plant-life, and end with animal-life. Some animals eat plants,some animals eat other animals. Three major parts make up foodchains Producers, Consumers, and Decomposers.

  5. 5. A food web is a combination of food chains that integrate to form anetwork . In nature, food chain relationships are not isolated. They arevery complex, as one organism may form the food source of manyorganisms. Thus, instead of a simple linear food chain, there is a weblike structure formed by these interlinked food chains. Suchinterconnected matrix of food chains is called food web. Food websare indispensable in ecosystems as they allow an organism to obtain itsfood from more than one type of organism of the lower trophic level.Click on the link to discover more information about food webs.Food web Video on How stuff workshttp://videos.howstuffworks.com/science/food-chain-videos-playlist.htm#video-27997
