Question

Suppose there were no animals in this world how wiukd this have affected the amoubt of oxygen and carbon dioxide in the air ?

Answer 1

All the animals are interdependent to each other,and plays an important role in the balancing of the environmental conditions.

Lets suppose all the animals from earth disappeared.

Respiration in animals: Animals take up oxygen and give out carbondioxide during respiration.

# Amount of OXYGEN will “increase” : since there is no animals to take up the oxygen given out by the plants, amount of oxygen in atmosphere will be abundent.

# Amount of CARBONDIOXIDE will “decrease” : Since animals have a role of givig back CO2 to the atmosphere,and since they have disappeared now,no one would be there to give back CO2 except some microorganism and humans.
