Is oxygen level higher in rainforest than desert?

No, oxygen levels are generally lower in rainforests than in deserts. Deserts receive less rainfall and have sparse vegetation, which means there is less plant matter to produce oxygen through photosynthesis. Rainforests, on the other hand, have abundant rainfall and lush vegetation, which leads to higher levels of oxygen production. However, due to the high temperatures and respiration of organisms in rainforests, the oxygen levels may still be lower compared to deserts.
