Aman riding his bike had a velocity of 5 meters per second north. after 10 seconds, his velocity increased to 9 meters per second north. what was his average acceleration? a. 0.4 meters/secb. 1.4 meters/2 secc. 40 meters/secd. 0.4 meters/2 sec

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is

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.
