Food Chain Definition Biology. A food web is made up of several food chains and a food pyramid includes energy flow up the food chain. “it is the process by which nutrients are transferred between the different species that make up a biological community.
A food chain also shows how the organisms are related with each other by the food they eat. Food chains consist of three types of organisms: This is the simplest way of showing feeding relationships.
In biology and ecology, we use the terms food web and food chain.
All food chains begin with a producer, which is consumed by a primary consumer, which is consumed by a secondary and then tertiary consumer, and ultimately maps the flow of energy throughout trophic levels. The food chain starts with the producer or plants that convert solar energy into the usable form of energy (food) by the process of photosynthesis which is then eaten by consumers. A food chain shows what eats what in a particular habitat. In contrast, food web is a complex pathway that indicates a number of food chains together to show how the organisms are interlinked with each other to survive.
