All organisms interact with their environment. choose one of the biogeochemical cycles and explain how various types of organisms are part of that cycle and recycle the substance in an ecosystem. provide one example of how human activity has impacted the cycle you have chosen and one step we can take to reduce human impact on the ecosystem.

Biogeochemical cycling moves a chemical substance through the biotic (living) and abiotoic (nonliving) components of earth.  There are many biogeochemical cycles.

One example of a biogeochemical cycle is the water cycle.  The water cycle describes how water on the earth evaporates and rises into the atmosphere.  Once it reaches the atmosphere, it cools and condenses into clouds.  From the clouds, the water falls back to the ground (precipitates) in the form of rain, snow, sleet, or hail.  Once on the ground, it can evaporate again into the atmosphere.
