What gives wind its mass? a) barometric pressure
b) air molecules
c) air pressure
d) the convection cell

air pressure

Explanation:

Air masses tend to flow from areas of high air pressure to areas of low air pressure. Thus, winds blow away from high-pressure areas; wind blows towards low-pressure areas. Air masses also move vertically.

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.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
