Match the statements with the correct element Photosynthesis and cellular respiration cycle carbon through living things and the atmosphere.
Cycle nutrients between living and nonliving parts of Earth
Other bacteria change ammonia (NH ) into nitrates and nitrites (nitrification)
Fertilizers with nitrogen help plants grow but runoff causes eutrophication in nearby water bodies
Human activity causes disruptions to the cycles.
Organic molecules
Burning fossil fuels releases carbon dioxide back to the atmosphere
Fossil fuels are ancient carbon stores
Animals respire carbon dioxide, which plants uptake.
Plants can use nitrates for nucleic acids and proteins
Maintain overall health of Earth
Decomposers return organic matter to the soil through ammonification
