The term food chain describes the order in which organisms, or living things , depend on each other for food. Every ecosystem , or community of living things, has one or more food chains.A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. Let's look at the parts of a typical food chain, starting from the bottom (the producers) and moving upward. At the base of the food chain lie the primary producers. Plants, phytoplankton, and organisms that look like plants, like algae, are all examples of producers. The food chain starts when these producers are eaten by other organisms. Some producers, like plants, get the energy they need to make food from the sun. Photosynthesis is the name for this process.Feeding (consumption). Energy flow. The transfer of substances such as carbon and nitrogen.

In a community which has producers, consumers, and decomposers, the energy flows in a specific pathway. Energy is not created or destroyed. But it flows from one level to the other, through different organisms.The food chain would be: plant → grasshopper → bird → snake → owl. A food chain cannot continue to go on and on. For example the food chain could not be: plant → grasshopper → spider → frog → lizard → fox → hawk. Food chains only have 4 or 5 total levels. Therefore, a chain has only 3 or 4 levels for energy transfer. A food chain is a system used to transmit energy from one organism to the next. When these systems are used in ecology, they are known as the food web. A food chain describes how a particular organism collects its food. In other words, a food chain is a sequence of who eats whom in a biological community or an ecosystem to obtain food..
