Answer:

Four abiotic forms of nitrogen cycle and its chemical formula

Ammonium – $NH^{4+}$

Ammonia – $NH^3$

Nitrite – $NO^2$

Nitrate – $NO^3$

Explanation:

Ammonium: In the nitrogen cycle ammonium is starting point that is present in soil and are converted to various forms by different process.

Ammonia: In the process of nitrogen fixation, the bacteria having nitrogenase enzymes reacts with the nitrogen as well as hydrogen and produces the ammonia, which is further converted to organic compounds.

Nitrite: The nitrosomonas bacteria present helps in conversion of nitrogen gas into nitrite.

Nitrate: Again the Nitrite is converted into Nitrate by the nitrobacter. During the process of assimilation ammonium and nitrate are absorbed by the plants.

bezimeni [28]

Cephalization describes the process by which organisms develop a distinct head. The head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. Cephalized organisms exhibit a distinct division between parts of the body; they have a front, back, top and bottom. These animals comprise the bulk of animals that are encountered on a daily basis.
