Answer & explanation:

1. In the nitrification process, the oxidation of ammonia (NH₃) occurs, converting it to nitrite and, subsequently, to nitrate. This process is performed by chemosynthetic bacteria (also known as nitrifying bacteria), that is, they use the energy released in nitrification to synthesize their organic substances.

2. Denitrification occurs when bacteria in the soil called denitrifiers use nitrates and turn them into nitrogen gas. Denitrification ensures the return of nitrogen to the atmosphere.

3. The fixation of atmospheric nitrogen occurs mainly with the help of bacteria. These bacteria form nodules in the cortical region of the roots of these plants, where they act by capturing atmospheric nitrogen and transforming it into ammonia (NH₃), which will be used by plants.

Answer from: Quest

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
