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.
What do you think will happen to animals and humans if the amount of oxygen in the air is reduced?
youll die
if photosynthesis stops animals will not get food to eat .The amount of oxygen will decrease and amount of carbon dioxide will increase and the ice will melt which can cause floods.
There would be hardly any left. If you got rid of trees too then I guess your stumped.
Nowhere, animals do not produce oxygen.
If plants take oxygen as they give out during the day the humen beings and animals were die
the amount of dissolved oxygen would decrease.
It is unlikely the Earth will run out of oxygen as long as there is an adequate amount of plant life and animals. Animals produce oxygen from the CO2 animals emit and vice versa.
Animals use the amount of oxygen relative to their size. An elephant would need lots of oxygen, as it has larger muscles. Whereas a mouse has considerably smaller muscles, so it would require less oxygen.
There would be no oxygen therefore no humans or animals.
