Biogeochemical cycles

• are significant for energy flow: the cycles allow transfer of molecules from one locality to another
• Are significant for nutrient uptake: this is essential for survival of organisms
• Are significant for environmental stability: maintain balance in the ecosystem, sustained health of biosphere
• Are significant for biodiversity: promoting balanced growth and limiting competitive exclusion
• Are significant for climate regulation: carbon effects temperature etc
• Reservoir pool is when chemical substance resides for a long period
• Exchange pool is the medium through a substance moves 1 place to another
