If there would be no animals in the world then the amount of oxygen on the earth would have increased 10 times. There would be no plants as there is no main source of carbon dioxide..only the plants that cactus...thorns...would be abke to exist. And then there will only be the presence of bacteria that is only bacteria exist...and It would be a truly slow, boring world...

Answer:If there were no animals in the world, the amount of carbon dioxide will decrease. Most of the plants would die as they have all the substances to photosynthesise. And so,they will die of hunger and because of that,oxygen won't be produced anymore. The remaining surviving plants would also die due to shortage of oxygen during the night. Slowly, there won't be any oxygen or carbon dioxide in the air.Only some bacteria who don't need oxygen to live will live.This is how it will affect the amount of oxygen and carbon dioxide in the air if there were no animals.
