Ecology: Cycles

Master Ecology Cycles: Carbon, Water, Nitrogen!

Oxygen Cycle Use the following words to fill in the blanks:Photosynthesis Respiration Oxygen Carbon dioxide Oxygen Respiration Carbon dioxide Photosynthesis Carbon Cycle Fill in the diagram using the following words some words may be used more than once:atmospheric carbon combustion respiration photosynthesis dissolved carbon dioxide fossil fuels decomposition atmospheric carbon photosynthesis fossil fuels respiration respiration decomposition dissolved carbon dioxide photosynthesis combustion Water Cycle Use the following words to fill in the diagram:precipitation condensation transpiration evaporation seepagegroundwater surface runoff ocean water precipitation surface runoff condensation evaporation ocean water transpiration seepage groundwater Nitrogen Cycle Use the following words to fill in the diagram:atmospheric nitrogen nitrates nitrites decomposer atmospheric nitrogen decomposers nitrites nitrates Disruption of Cycle: Natural and Artificial Forest fires release the carbon, nitrogen, phosphorus, and sulfur sequestered in the biomass of the trees.Decomposition releases chemicals from deceased plants and animals that obtained carbon, nitrogen and other chemicals in their bodies.Landslides and earthquakes can alter the land and change the course of rivers, burying or releasing carbon, nitrogen and other chemical and disrupting cycles.Volcanic eruptions add carbon, nitrogen and other chemical into the atmosphere.
