Answer #1

Answer:

8). D. Nitrification

Explanation:

  • is the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of the nitrite to nitrate.

19). D. a+b

Explanation:

  • or Mineralization is performed by bacteria to convert organic nitrogen to ammonia.

Arbuscular mycorrhizal (AM) fungi are root symbionts that might improve the ability of plants to compete for organic nitrogen products against other decomposer microbes. However, AM uptake of organic nitrogen, especially in natural systems, has traditionally been difficult to test.

20). D. Mineralization

Mineralization occurs in soil as microorganismsconvert organic nitrogen to inorganic forms.

21). C. Woth low nitrogen content

Leaves usually take 6 to 12 months to break down into compost on their own because they don't contain the nitrogen necessary to speed the composting process.
