Susan goes outside to measure the light intensity that different parts of her yard receive. She notes that part of her lawn receives sunlight at an intensity of 250 and other parts receive sunlight at an intensity of 450. The grass that receives the intensity of 450 is three times taller than the grass receiving the 250 intensity. She decided that she will increase the light getting to the grass by cutting down a few trees to get the shirt grass to grow. Which organelle is affected in this environment?
A. Cell Wall
B. Chloroplasts
C. Mitochondria
D. Nucleus

B.Chloroplasts

because I took a test on this question and got it right

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.
