There was no oxygen in the beginning. Plant life developed and released oxygen gas into the atmosphere over a long period of time.
If that had never happened, there would not be much if any free oxygen in the atmosphere and aminal life as we know it would never have developed.

Can animals produce oxygen?
No. Animals do not give plants oxygen. Plants release oxygen as a byproduct of the photosynthesis process by which they take in carbon dioxide and release oxygen. Animals and humans give plants carbon dioxide.
What gas is needed by animals to breathe in?
Animals need AIR to breath in - AIR is made up of about 80% Nitrogen and 20% Oxygen. The animals use the Oxygen in the AIR.NOTE if an animal were to breath 100% Oxygen this would eventually kill it, Pure Oxygen is toxic.They need to breath AIR.
What would happen to animals if the amount of oxygen the earths atmosphere decreased?
youll die
What kinds of animals might have survived the period of reduced light?
Animals that would have survived on reduced light would be those that are meat eaters. Of course, they wouldn't have survived long because plants would dies and they wouldn't have oxygen.
What factor would be least likely to limit the types of animals that can survive in an aquatic habitat?
the level of oxygen dissolved in the water.
What do animals need but plants don't?
That would be oxygen.
Do all animals use the same amount of oxygen?
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.
What would plants and animals use the energy that was lost?
oxygen
Can animals produce oxygen?
No. Animals do not give plants oxygen. Plants release oxygen as a byproduct of the photosynthesis process by which they take in carbon dioxide and release oxygen. Animals and humans give plants carbon dioxide.
If you woke up tomorrow and all of the animals on earth were gone what would happen to the amount of oxygen in the air?
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.
Can oxygen turn into gold?
No we would have been filthy rich if that happened

Why is photosynthesis so important to animals?
one of the ways in which photsynthesis is vital to animals is that CO2 is recycled into oxygen. Without this recycling process there would be less oxygen for animals to undertake respiration.
What will happen if there was no trees and plants?
There would be no oxygen therefore no humans or animals.
Why would animals die if plants didn't produce oxygen?
All animals depend on oxygen, because oxygen is needed for respiration and converting food to energy, and the by products will be carbon Dioxide (CO2) which plants use.
What would happen if lily pads were removed from pond?
The wetland would be warn away by erosion.
What would happen if all the oxygen in the air?
we all die lol Everything that needs oxygen would die. including us, animals, and plants.
