The answer is A.
The answer is A because that is the only positive of the entire set of answers.
B has a negative word of pollution which is something we are currently trying to stop.
C has threaten which would make other fish populations threatened or other aqua culture
And D has diseases which is obviously negative for the fact that diseases causes death and will ultimately lead to an endangered or extinct species if mutations or adaptions are not made.
Hope this helps!
Explanation:
the first step in nitrogen cycle is formation of nitrates it is done by following ways.1. NITROGEN FIXATION: conversion of nitrogen into nitrates is called nitrogen fixation. it is done by three ways which include atmospheric nitrogen fixation(done by thunderstorms and lightning),biological nitrogen fixation(done by nitrogen fixing bacteria),industrial nitrogen fixation(done in industries). 2.AMMONIFICATION AND NITRIFICATION: ammonification is the breakdown of proteins and nitrogeneous wastes and nitrification is conversion of ammonia into nitrates and nitrites this procces is done by bacteria. the second step is assimilation in which the nitrates formed in the above procces are used by plants and in the third procces which is denitrification in which the nitrates are again converted into atmospheric nitrogen.
