Bears carry the nutrients of the salmon they eat into the forest. This actually completes the mineral cycle. Minerals start in the forest and are carried by the rains into the streams, then rivers, and finally into the ocean. The salmon take the minerals from the ocean environment and carry them back to the streams and rivers where they are eaten by the bears. The bears carry these minerals back to the forest when they defecate or die. If this cycle was not complete the forest would eventually not have enough of the nutrients needed to be healthy.
