5. When you scuba dive, the added pressure due to the water varies directly with your depth. At 20 feet, the added pressure is about 9 pounds per square inch (psi). If an amateur diver can safely stand an added pressure of 30 (psi),
how deep could he or she dive? A sunken submarine lies in 120 feet of water. How much added pressure would a
diver experience in going to the submarine?

the answer is b

explanation:

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.

not too sure but maybe in the hot springs.
