Breathing

I could find nothing in this article about oxygen being the reason we breath, and it being the element that combines with food to produce the energy to keep us alive. Am I wrong? Did I over look it? A huge number of readers will not know this, and this is the most important feature of oxygen from our point of view. So I added it to the introduction, which should always contain the information that readers will find the most important. Nick Beeson (talk) 23:38, 5 February 2023 (UTC)[reply]

It is covered in Oxygen#Photosynthesis_and_respiration. –LaundryPizza03 (d c̄) 03:21, 10 February 2023 (UTC)[reply]

It might be stated better that the reason we breath at all is precisely because of the prevalence of dioxygen (or rather life evolved to breath dioxygen because 'it is there' and it is suitably reactive) (Andy Loates). 81.155.194.247 (talk) 00:47, 27 September 2023 (UTC)[reply]

The sentence "The body's circulatory system transports the oxygen the cells, where cellular respiration takes place." is missing the word "to". It should read "The body's circulatory system transports the oxygen TO the cells, where cellular respiration takes place." ChiCub08 (talk) 21:39, 30 April 2023 (UTC)[reply]

Oxygen-15 natural occurrence

Shouldn't oxygen-15 be listed as "trace" rather than "synthetic" , since trace ammounts are produced naturally by lightning and in the sun. 174.103.211.189 (talk) 04:20, 7 December 2023 (UTC)[reply]

oxygen is not the most abundant element on earth. iron is

thought that should be changed 2605:A601:AA0D:F900:9CA4:FB25:36E:D726 (talk) 05:51, 6 January 2024 (UTC)[reply]

Oxygen is the most abundant specifically on Earth’s crust 99.17.2.140 (talk) 08:50, 16 January 2024 (UTC)[reply]

Define abundance. By number fraction, i.e., actual number of atoms, oxygen is by far more abundant over the entire Earth. There is a greater mass fraction of iron but that's simply because it's heavier. However, as stated in the article, there is a greater abundance of oxygen by mass in the Earth's crust and biosphere.
