Food Chains Examples

A food web is an illustration of the direct line of food source, starting with the lowest level of the food chain, which is often single-celled organisms or plant life, and advancing to the uppermost levels of higher mammals and other predators. Food chains are often demonstrated in conjunction with food webs, which illustrate the interconnectedness of many species that consume more than one food source, such as fish eating plants, insects, and smaller fish, or hawks eating mice, rabbits, and snakes.

Food chains and webs exist in every type of ecosystem and biome, from land dwellers to aquatic or aerial environments, even to microscopic or chemical environments.
