Sedimentary rocks are formed when soil, rocks, or the remains of dead organisms undergo layering and compaction over a long period of time. the mass of the sedimentary rock is equal to the mass of the a) the soil and rock parts. b) organic materials in the rock. c) inorganic materials in the rock. d) the original items making the rock.

it is D.

Sedimentary rocks are formed when soil, rocks, or the remains of dead organisms undergo layering and compaction. During these processes, mass is conserved. The materials needed to form a certain amount of rock is equal to the mass of the all the original parts making the rock.

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.
