systems
B. Computer models analyze many pieces of data in a short time.
ООО
C.
mputer models require valid data to make accurate predictions.
D. Computer models test hypotheses by simulating different
situations.

C

Explanation:

I would say C because it HAS to have valid data. Which is a limitation especially if you can't get that data.

a, i am pretty sure.

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.
