Evgen [1.6K]

Answer:

Ammonification

Explanation:

The ammonification is part of the nitrogen cycle. This process occurs when the plants and animals die. The dead plants and animals start to decompose because of the organisms like the fungi and bacteria that manage to decompose them. As they are decomposed, the nitrogen is converted into ammonium by the decomposers. The ammonium is returned into the soil, thus becoming available for the living organisms that can extract it from it, and in that manner continuing the nitrogen cycle.

zimovet [89]

Answer:

High-protein

Explanation:

  • Chronic obstructive pulmonary disease is a disease in which there is obstruction of the lungs which makes it difficult for the person to breathe and there is an improper flow of the air in the respiratory tract.
  • The disease management involves a proper diet which should have a high amount of proteins in it.
  • A high protein diet is recommended for the patients as this leads to the strengthening of the muscles involved in the respiration and thus, avoids wasting and slows down the progressive worsening of the disease.
  • Further, the high protein diet also helps to strengthen immunity and prevents infections of the respiratory tract.
  • The proteins also provide more energy as sufferers of the disease also have difficulty performing activities such as walking, running, etc due to shortness of breath.
