Nutrient Cycles
All of the life on earth revolves around a few key nutrients and in combination with energy form the sun it is theses
nutrients which are required by all of earth's producers. These nutrients are essentially contained within a closed
system on earth, which means no nutrients enter or leave the biosphere in large quantities. For this reason there is a
limited amount of the essential nutrients available to the producers, so the available nutrients such as carbon, nitrogen
and phosphorus must be recycled and reused by organisms.
Use sketches, arrows, and words to show the sources of the nutrients in the cycles below. In each case you need to note
how humans influence each of the cycles. Be able to explain where the major sources of each nutrient come from and
how their levels change
