Answer:
sound: because sound we can hear it, when someone says something to you, you can hear it but you cannot you cannot touch it
Depends on what mountain you are on
If you are on Everest, then the amount of effective oxygen available would be 6.9% (0 altitude would be 20.9)
that is why anyone should always bring oxygen tanks when climbing a high mountain
Without photosynthesis, there wouldn't be any sugar or o2 which kick off the respiration reaction. Without respiration, plants would use up all the CO2 and die to extinct.
<h3>What is photosynthesis?</h3>
The photosynthesis is a process that occurs in the chloroplast organelle of the plant cells. The typical light reaction of the photosynthesis takes place inside the thylakoid membrane of the chloroplast.
The chief reactants such as water and carbon dioxide participate in the reaction. The water gets oxidized in the reaction to release the oxygen as a product. The carbon dioxide get reduced.
Thus, Photosynthesis requires the products from respiration, and respiration requires the products from photosynthesis.

Answer:
Both photosynthesis and cellular respiration occur in plants. However, the rate of photosynthesis exceeds that of cellular respiration during the day when there is sunlight. The Chlorophyll pigment picks up energy from the photons and uses it to reduce carbon dioxide into carbohydrates. During the night, when there is little sunlight, the rate of photosynthesis drops down below that of cellular respiration, that breaks down these energy molecules made in photosynthesis to supply the plant’s cellular processes with energy.
