The night

Explanation:

Remember that a plant does two things, it either produces energy by photosynthesis, in which case it takes up the carbon dioxide and releases oxygen, or consumes energy to grow/carry out the functions of life.

In the second case, the plant takes the glucose, or sugar, that it made during photosynthesis and breaks it into pieces, releasing energy. This step is accompanied by the release of carbon dioxide into the atmosphere. This happens all the time, but since the plant does not produce sugar and release oxygen during the night, the night is when it produces more CO2 than O2.

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.
