Answer:
All plants need 3 main things; water, air, and the proper temperature (they also need soil).
If you change any of them for instance let's say you change the temperature. Then, for example, corn won't grow successfully under cold temperatures.
If you don't give them enough water, they will die because of not enough water, and if you give them too much water, they will drown and die.
If you change the air pressure or the air you give them, (like you don't give them enough carbon dioxide), well you get the idea.
So if you change one of the three necessities, the seed won't germinate successfully or even die.
