• decomposers nitrogen cycle- converts protein and urea- ammonia
• respiration carbon cycle- animals+plants-co2
• decomposition carbon cycle, breakdown of organic material by microorganism such as bacteria and fungi (saprophytes)
• combustion carbon cycle, the process of burning something fuel+oxygen- carbon dioxide+water
• photosynthesis carbon cycle- co2- plants
• nitrogen fixing bacteria converts nitrogen gas in the air into nitrates
• nitrifying converts ammonia- nitrites- nitrates
• denitrifying converts nitrates back into nitrogen gas
