A trophic level can be defined as the position that occupies given groups of organisms in a food web. Labeling a carnivore as a heterotroph would be correct. If the flow of energy in an arctic ecosystem goes through a simple food chain, perhaps involving humans, starting from phytoplankton to zooplankton to fish to seals to polar bears, An arid desert ecosystem does not have a consistent water supply, so its primary producers, such as algae and lichen, spend some periods of time in an inactive state. Organisms at the top of the chain eventually die and are then consumed by decomposers, which fix the nitrogen levels and provide the organic material necessary for the next generation of primary producers.
