Biogeochemical cycles1

Biogeochemical Cycles

  • Remember the law of conservation of matter… Matter cannot be created or destroyed – therefore, the CYCLING of water, carbon, phosphorous, nitrogen and sulfur only makes sense, right?

  • Note that these elements cycle through ABIOTIC and BIOTIC portions of ecosystems!


Instructions for viewing this ppt

Instructions for viewing this ppt:

  • STUDY the different ways that the element passes between the atmosphere (if at all), the water, the soil, and living things

  • CLICK on the hyperlinks at the bottom of each graphic for animations and narrated explanations of each cycle

  • Inferwhat the impact of human activity would be on each cycle!
