There would be hardly any left. If you got rid of trees too then I guess your stumped.
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 would all die because of all the carbon dioxide in the air and no plants and trees to take in the carbon dioxide to make oxygen
we will die because there is no oxygen to breathe in
If plants take oxygen as they give out during the day the humen beings and animals were die
Yes, plants are the main source of oxygen.
Most of autotrophic plants get major amount of oxygen from photosynthesis. During night, when there is no photosynthesis, oxygen by plants is obtained from air However, the amount of oxygen released during photosynthesis by plants is manifold of their requirement for respiration.
try something like "Today's plants are tomorrow's oxygen"
Plants reduce the amount of carbon dioxide in the air and increase the amount of oxygen.
Humans would die, because plants make our oxygen
it would change by the oxygen going low down
We will survive! All we need is sunlight, plants for oxygen!
There would be no oxygen therefore no humans or animals.
