The organisms found in the littoral zone are critical for the biological cycling of abiotic factors. This video explores the complex relationships between primary producers, lower level consumers and higher order consumers and how they can be modelled using food chains and food webs. Informative diagrams and in-the-field footage make this an essential resource for senior secondary biology students.
