This energy pyramid, like all others, shows the transfer of the Sun's energy as it passes thru different organisms. The White Spruce utilizes 100% of the Sun's energy. When it is eaten by the Moose, 10% of the Sun's energy from the White Spruce is utilized by the Moose. When the Moose is eaten by the Wolf, the Wolf only utilizes 1% of the Sun's energy found in the moose from the White Spruce. Energy is lost throughout the stages because only 10% of the energy from the previous level is passed on to the next. therefore, Wolves must eat more than a Moose to acquire the same amount of energy.
