plants
Flowers do not use oxygen in the same way animals do for respiration. Instead, flowers use oxygen produced during photosynthesis to break down molecules for energy and growth. The oxygen produced during photosynthesis is often released back into the atmosphere.

Oxygen is itself a chemical element.
Most of the worlds oxygen is produced by Trees.
The CO2 produced by the Krebs cycle is a waste product; it is disposed of as waste. In humans, we breath in oxygen with our lungs, use that oxygen in cellular respiration, and breath out the waste CO2. It should be noted that air is not made entirely of Oxygen and carbon dioxide, and that our bodies are not efficient enough to consume all of the available oxygen in each breath, and that therefore, what humans exhale is not 100% CO2.
Human beings breath in oxygen, and breath out CO2. The plant's leaves, when making photosynthesis, use CO2 and a few other things to make photosynthesis. When finished with making photosynthesis, the leaves release some oxygen, which is the gas we use to breathe. Thus, oxygen is the useful gas made by photosynthesis.
If all the plants in the world die, then we could'nt breath, because no oxygen would be produced
a lot of oxygen! that's where most of it comes from!

The colorless, odorless, and tasteless gas that we breathe in is oxygen (O₂). It is essential for the survival of most living organisms, as it plays a crucial role in cellular respiration. Oxygen is produced by plants during photosynthesis and is vital for energy production in our bodies.
The oxygen produced by photosynthesis is released into the air where it may combine with other chemicals to form oxides, or may remain in the air as O2 and be breathed in by animals where it is converted to carbon dioxide.
animals usually depend on plants for oxygen. we breath out carbon dioxide and breath oxygen in, same with animals. and plants breath that carbon dioxide in and and breath out oxygen.
