The cells in this leaf are making their own energy by the process of a
respiration, where oxygen and sunlight at Q and R are taken in and then converted into carbon dioxide and glucose at S and T.
b
photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and oxygen at S and T.
c
photosynthesis, where glucose and oxygen at Q and R are taken in and then converted into water vapor and thermal energy at S and T.
d
respiration, where carbon dioxide and oxygen at Q and R are taken in and then converted into thermal energy and methane gas at S and T.

B is the answer. Glucose and oxygen are given off during Photosynthesis

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.
