Arctic Fox

Polar Bear

NORTH POLE FOOD CHAIN

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

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.

when the Polar Bear passes away, its body is then decomposed by bacteria in the water

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.
