it would change by the oxygen going low down
Animals and humans would die because there would be insufficient amount of oxygen in the air.
The oxygen that plants make is taken up by humans. The humans take the oxygen and transform it into carbon dioxide. When the humans do this then the plants take it and change it back into oxygen. This is a never-ending cycle, without plants, humans and animals would die out, without humans and animals, plants would die out.
If plants take oxygen as they give out during the day the humen beings and animals were die
I would think so. At night plants consume a small amount of carbon dioxide, to supplement the energy that they get from the light during the day. But don't worry, they only consume a small fraction of the amount of oxygen they produce throughout the day. So I would say yes they do consume oxygen in the dark.
we will die because there is no oxygen to breathe in
The atmosphere in an area where a disease killed all the plants would not have any or very little oxygen. Trees would still produce some oxygen.
Humans need to bring food, water, oxygen,
if all the animals were gone there would be no carbon dioxide for plants and trees to take in and no oxygen would be produced.
we all die!! As there would be no oxygen which is produced by plants and trees.
As a byproduct of photosynthesis, plants produce oxygen. A decrease in plants would mean a decrease in the amount of oxygen being released into the atmosphere, although such a decrease would have to be large in order to produce a noticeable effect.
i think there would be less oxygen because the plants take in carbon dioxide and release oxygen
the amount of dissolved oxygen would decrease.
