Abstract Although it is easy enough to describe in theory the functioning of any community in terms of simple linear food chain, with herbivore feeding on primary producer, carnivore feeding on herbivore, etc., in practice, the interrelationships between populations are so complex that they can be considered more accurately as a web, rather than a clhaun. Consequently, the energy does not flow directly from one trophic level to the next, but meanders within the various trophic levels. |
