A food web is a system of overlapping food chains. A food chain is a sequence of organisms showing who eats whom in an ecosystem. An ecosystem has many food chains that are interconnected. An animal can be eaten by many different animals and therefore be a part of many different food chains. Organisms of a food web are linked by arrows to indicate the direction of energy transfer. Energy, in the form of food, passes as an organism from a higher level consumes an organism from a lower level. Owls are predators which prey on rodents, shrews, moles, insects, reptiles and small birds. Since very few predators feed on owls, they hold the top position of the food chain.
