Answer:
The main sources of water in Central Asia are the Syr Darya and Amu Darya Rivers, mostly fed by snow- and glacier-melt from the Pamir, Hindu Kush and Tien Shan mountain ranges.
Explanation:
"Ammonification" is NOT a process that drives the carbon cycle.
<u>Option: B</u>
<u>Explanation:</u>
The organisms circulate carbon-di-oxide in carbon cycle by going through respiration, decomposition, sedimentation, and photosynthesis process but not ammonification. Basically the actual source of nitrogen is agricultural, when a plant or animal passes or an animal disperses waste.
In the remains, bacteria or fungi turn the organic nitrogen back into ammonium, a cycle called ammonisation or mineralisation. Then the micro-organisms generate metabolically required energy from organic nitrogen oxidation into ammonium. Ammonium is then essential for assimilation and absorption into amino acids or for use in other metabolic applications.
DNA I’m not sure if im right sorry if im wrong
