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 Water Cycle Human Impact on this Cycle Carbon Cycle Human Impact on this Cycle Ecology: Ch 3 Cunningham & Cunningham Name: _____________________________________ Date:_________________ Nitrogen Cycle Human Impact on this Cycle Phosphorous Cycle Human Impact on this Cycle Sulfur Cycle Human Impact on this Cycle Ecology: Ch 3 Cunningham & Cunningham Name: _____________________________________ Date:_________________
