- Animals will come back.
- The ecosystem will slowly rebuild.

Answer:
I am positive the answer is C because I used to study the exact same lesson.
Answer:
glutamine synthetase-glutamate synthase
b)Glutamate dehydrogenase catalyzes the same reaction, but only under conditions of very high NH4+ levels such as agricultural fertilizers since the reaction is unfavorable under standard conditions (ΔGº’ = +30kJ/mol). Under physiological conditions, this reaction deaminates glutamate.
Explanation:
The importance of the first reaction you can see that it needs a molecule of ATP in order to create the catalysm, so that´s why that enzyme is called synthetase, since it needs a molecule of ATP to do its work, the other one, the glutamate synthetase, because it does not need the molecule of ATP to do so.
Glutamate can only catalyze the reaction under certain not found in nature regularly conditions, that´s why it doesn´t work as a dehydrogenase.
