What is the role of photosynthesis and respiration not gases in our atmosphere

Gravity holds in place the gases that form the Earth's atmosphere, and the survival of life on the planet hinges on the right balance of these gases. In photosynthesis, plants constantly absorb and release atmospheric gases in a way that creates sugar for food. This process plays a critical role in maintaining a healthy, life-promoting atmosphere.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
