The oxygen we breathe comes from the process of photosynthesis in plants, where they convert carbon dioxide and water into glucose and oxygen. The oxygen gas is released as a byproduct of this reaction.
When two atoms of the same element come together, they form a molecule of that element. For example, when two oxygen atoms come together, they form a molecule of oxygen (O2).
Three atoms of oxygen come together to form an ozone molecule (O3). This molecule is responsible for protecting Earth by absorbing and blocking harmful ultraviolet radiation from the sun in the stratosphere.
The oxygen atoms in water (H₂O) come from the air we breathe. When we inhale, our lungs absorb oxygen from the air. This oxygen is then used in the process of cellular respiration to produce energy for our body's cells.
The oxygen your body needs comes from the air you breathe. When you inhale, your lungs take in oxygen from the air, and this oxygen is carried to all the cells in your body through your bloodstream to be used in various metabolic processes.
A molecule of water, a molecule of hydrogen, a molecule of oxygen, a molecule of sugar... Actually more substances come in form of molecules than in atomic form.
From the CO2 molecule.
Water
They come from plants. It is a cycle. (Carbon Dioxide and Oxygen Cycle) When you breathe out you realse Carbon Dioxide and the plants sucks it in and relase oxygen and that is what we breathe in.
Oxygen is an atom. What you breath on a regular basis is O2
No, they aren't a mammal like a whale or dolphin so they breathe using the oxygen in the water.
animals breathe oxygen, as you know, and exhale carbon dioxide. plants, trees for example, take in carbon dioxide and release oxygen. this is why there is plaenty of oxygen left for every living creature

The ozone originally comes from the oxygen gas. It gets converted into ozone by UV rays.

No they do not. That's why they come up every once in a while. Mammals are animals that MUST breathe air to survive. All otters areammals
