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.
Life as we know it would not exist.
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.
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.
youll die
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.
the level of oxygen dissolved in the water.
That would be 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.

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 all the animals were gone there would be no carbon dioxide for plants and trees to take in and no oxygen would be produced.
No, oxygen cannot turn into gold. Gold is a chemical element with a unique atomic structure that cannot be produced by simply adding or changing the atoms present in oxygen molecules.

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.
There would be no oxygen therefore no humans or animals.
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.
The wetland would be warn away by erosion.
we all die lol Everything that needs oxygen would die. including us, animals, and plants.
