If more carbon dioxide was made available to a plant, what would be the
effect on the rate of photosynthesis?
A. The rate would be unaffected.
B. The rate would increase.
C. The rate would decrease.

B. The rate would increase.

Explanation:

Increased carbon dioxide concentration increases the rate at which carbon is absorbed into the carbohydrate in an independent reaction, so the level of photosynthesis usually increases.

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.
