Of course it is the reason. Oxygen is made by photosynthesis mainly
Yes, that is correct. Without plants we would not have evolved as we have. We might look different and act differently.
Yes that is the reason. It absorb CO2 and emit O2 gas.
Yes it is the reason. Oxygen began to form through it
Well Photosynthesis is the only way or process that provides the Oxygen to the world. Tree in the earth and all the green photosynthetic bacteria (Cyanobacteria) and alga are the natural soource that provide the Oxyden to the world by photosynthesis.
photosynthesis : carbon dioxide + water --> oxygen + glucose this is how plants get the glucose and are "the lungs of the world".

In photosynthesis, 6 molecules of H2O are used along with sunlight and 6 molecules of CO2. This then gets converted into sugar and 6 O2 (oxygen) this is how the world get's our oxygen and energy. Hope this helps!!
During the hours of sunlight, trees absorb the gas carbon dioxide in carrying out the first stage of photosynthesis. Carbon dioxide is the gas that is being blamed as the cause of global warming, therefore trees reduce the amount that remains in the atmosphere - considered to be a good thing. When the process of photosynthesis is complete trees then release oxygen as a by-product into the atmosphere. Since all of sentient life relies upon oxygen this is considered to be a good thing also.
Photosynthesis and cellular respiration. Without these two things the world would not be alive!
Most autotrophs produce food through photosynthesis. This is the process of using carbon dioxide and water to produce glucose and oxygen. Photosynthesis needs sunlight to proceed.
Photosynthesis is arguably the most important chemical process in biology because it converts light energy into usable chemical energy for life on Earth. It also produces O2 (oxygen) gas which is critical in cellular respiration. With the exception of a few species, life on Earth depends on photosynthesis.
Plants undergo photosynthesis which rids the world of the carbon dioxide that animals and people expel due to cellular respiration, and convert it into oxygen. We breathe the oxygen as we need it to survive.
repiration removes oxygen from the atmosphere and releases carbon dioxide into the atmosphere Photosynthesis does the opposite.. if respiration exceeds photosynthesis then the levels of oxygen gas would gradually decrease. however this is ignoring all the other factors affecting the oxygen concentration. the ocean for example, acts as a buffer until it reaches equilibrium an it acts as a buffer by removing co2 from the atmosphere.. there are many other factors to consider. including industry and mankinds actions..

I wouldn't be certain about all animals but I know that when cats and dogs eat things like grass it improves their digestive flow.
