At a depth of 50 m below sea level a human will experience a pressue of how many atmosphere

The pressure at a depth of 50 meters under the sea is 5 atm.

Explanation:

The pressure at the sea level is 1 atm.  When we go deeper into the sea the height of the water column increases and the pressure keeps increasing. The pressure increases by 1 atm after every 10 meters.

Therefore the pressure at 50 meter depth is 50/10  atm  which is 5 atm.

Any kind of organism living at greater depths in the ocean must adapt to the high pressure at the depths. Absence of air bladder in deep sea organisms is one such adaptation. Scuba divers also should use mechanisms to cope up with the high pressure at depths.

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.
