Lipid

Explanation:

Lipid is known as a hydrophobic organic compound composed mainly of carbon and a high ratio of hydrogen to oxygen.

They usually form a large macromolecule and known to be insoluble in water and soluble in substances such as alcohol, ether which makes it non polar substances.

They are however very important and are major constituents of plants and animal cells

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.
