30 points worthy plato user answers match each step in the nitrogen cycle to its description. __bacteria convert nitrates into nitrogen gas. __plants and animals take in and use nitrogen compounds. __bacteria break down waste products and return nitrogen to the soil. __bacteria convert atmospheric nitrogen to ammonia. __bacteria convert ammonia to nitrites and nitrates. a. nitrification b. nitrogen fixation c. ammonification d. assimilation e. denitrification

The nitrogen cycle is a cycle by which the nitrogen is converted into forms which are utilized by the living organisms and  these forms circulates among the atmosphere, biosphere, and marine ecosystem. The conversion of nitrogen is through biological and physical processes.  

Nitrogen Fixation  is the first step in nitrogen cycle. It involves the conversion of atmospheric nitrogen into ammonia. This is done by bacteria like Azotobacter and Rhizobium.

Assimilation  involves the absorption of ammonia by the plants from the soil.

Ammonification  is the process by which the dead organic remains of plants and animals are decomposed by the soil bacteria to produce ammonia.

Nitrification  is the process in which the ammonia is converted into nitrates by the soil bacteria Nitrosomonas and Nitrococcus. The nitrates are again converted into nitrites by the bacteria Nitrobacter.

On the basis of above description, the following is the match of steps of the nitrogen cycle.

A. Nitrification - bacteria convert nitrates into nitrogen gas.

D. Assimilation - plants and animals take in and use nitrogen compounds.

E. Denitrification - bacteria break down waste products and return nitrogen to the soil.

B. Nitrogen fixation  - bacteria convert atmospheric  nitrogen to ammonia.

C. Ammonification - bacteria convert ammonia  to nitrites and nitrates

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

answer: they produce more slow than unicellular organisms.
