The Nitrogen, Carbon, and Water Cycles

All living things use_Nitrogen____ to survive. ___nitrogen___________ gas travels from the ___air___ to the ___soil______. ______bacteria___________ turn nitrogen gas into ________ammonia_________. _____nitrification____________ is the process that transforms nitrites into nitrates (nitrites = 2 oxygen atoms & nitrates = 3 oxygen atoms). Special bacteria called _____*(denitrifying bacteria)/ decomposers ?*_________________ release nitrogen back into the nitrogen cycle and transform nitrates into nitrogen. _______Carbon_____________is an element found in every living thing on earth. When animals and humans breathe in oxygen and breathe out carbon dioxide it’s called ____respiration___________. _____photosynthesis_________________ is when plants use energy from the sun to turn water and carbon dioxide into food. When we ________ burn fossil fuels ___________  ____________ the carbon inside is released into the atmosphere. The excess carbon that is released into the atmosphere adds to the ___________global warming________  _________________ and ____the greenhouse effect__________ _____________. The sum of all water on Earth and in its atmosphere is called the _____hydrosphere________________. Oceans, the atmosphere, and groundwater are all _________reservoirs__________ in the water cycle. ____runoff____________ occurs when rainwater contributes to the flow of rivers and streams. This reservoir in the water cycle contains the most water: __Oceans_____________. Molecules of groundwater can stay in the ground anywhere from __Days____ to ___Years___________. 

*Decomposers are bacteria and fungi that turn dead things into Ammonium (NH4+), but they don’t directly release nitrogen back into the atmosphere, so that’s the only answer I’m not sure about.
