Cycles of Matter Energy flows one way…matter is recycled

1. The Water Cycle Evaporation Condensation Precipitation

What is a Nutrient? Chemicals that an organism requires to survive

Nutrient Cycles What nutrients are recycled through the biosphere? Carbon dioxide Nitrogen Phosphorus Potassium

Carbon Cycle CO2 gas in atmosphere taken up by plants Released by living things into atmosphere because of respiration

Nitrogen Cycle Atmospheric nitrogen fixated by bacteria Heterotrophs eat it Living things die and microorganisms return N to atmosphere

Phosphorus Cycle
