A food web, or food chain, is the feeding connections between organisms in an ecosystem. For example, birds of prey eat rodents, which eat insects, that in turn, eat plants. In addition to affecting humans, pollution impacts wildlife all around the world, from the polar bears in the Arctic to fish in a local watershed.
