In the Arctic ecosystem, energy transfer begins with algae and bacteria, which are consumed by krill and other small crustaceans. These primary consumers serve as the base of the food chain, passing energy to secondary consumers like the arctic cod.
the Polar Bear holds the tertiary spot, and for the last time through consuming, the energy and heat that started as algae, is passed into the Polar Bear's system.
the secondary consumer, or in the food chain, the arctic fox prays on the fish, and once again the heat and energy is passed on the fox.
when the Polar Bear passes away, its body is then decomposed by bacteria in the water
arctic cod pray off of the bottom feeders such as krill, passing the heat and energy they have obtained onto the arctic cod
krill feed off the algea and bacteria in the water, consuming the energy and heat from them
