"Translation", means to render something into a different form. This word is commonly used because RNA is using the code on the mRNA to make protein. It's like amino acids are like letters of a protein language, every 3 codons of the RNA are the letters of the RNA language.

<u>Answer</u>:- The three forms of nitrogen in an aquarium are
1. Nitrate NO3-
2Nitrite NO2-
3. Ammonia NH3
<u>Explanation</u>:
- The waste products produced by fishes is broken down into ammonia which is highly toxic for the fishes present in the aquarium.
- The nitrogen cycle takes place in the aquarium to convert this toxic <em>ammonia</em> into lesser toxic forms.
- This nitrogen cycle proceeds to convert ammonia into <em>nitrite</em> and then nitrite into <em>nitrate</em>. This means the cycle is ammonia——>nitrite——> nitrate.
- This conversion takes place with the help of several bacteria which establish a colony in the filter bed of the aquarium in the presence of ammonia .Then these bacteria help to finally convert ammonia to nitirite and then to nitrate.
- The bacteria that convert ammonia to nitrite are oxygen loving bacteria called as <em>Nitrosomonas</em>. The nitrite so formed is less toxic as compared to ammonia.
- The conversion of nitrite to nitrate takes place by the bacterial species called as <em>Nitrobacter</em> . The nitrate thus formed is harmless for the aquarium fishes at low levels.
Thus, in this nitrogen cycle we can see that<em> there are three different forms in which nitrogen is present- ammonia, nitrate and nitrite.</em>
