It’s the 3rd one! The O + O!!
<span>A fast-flowing river of air that forms when two air masses of very different temperatures meet is called a jet stream :)</span>
It's called t<span>he trachea.</span>
Those are glucose, oxygen and carbon dioxide (CO2).
<span>Respiration and photosynthesis are opposite processes in the plant cell. Photosynthesis makes the glucose and releases oxygen and they are used in cellular respiration to make ATP. The glucose is broken down during the respiration into CO2, which is used in photosynthesis. While H2O is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form H2O. </span>
Answer: Ecology!
I hope that this helps! :)
