Explanation:
1.) it provides oxygen for humans and carbon dioxide for plants
2.) it keeps the earth warmer than it would be without the atmosphere
3.) it protects us from radiation and meteoriods

Answer:
C. oxygen
Explanation:
Oxygen is needed to help the process of turning glucose into ATP. The initial step releases just two molecules of ATP for each glucose.
Given what we know about the use of spectrums, we can confirm that the positions of peaks and dips provide information as to the elemental composition of the object in question.
The question asks about the dips and peaks of a spectrum, which allows us to assume we are dealing with Infrared spectroscopy and IR spectrums. This is defined as the measurement of how certain matter interacts with infrared radiation.
These graphs are used to measure how this matter absorbs, reflects, or even emits said radiation. Therefore, the use of spectrums allows us to infer as to the chemicals present or functional groups of an object, and therefore its elemental composition.
When looking at the spectrum graph, we will see that at times the curve dips down, which indicates that <u><em>less light </em></u>is transmitted. That means light is being absorbed. Due to the fact that bonds absorb different frequencies of light, <u>the </u><u>peaks </u><u>tell you what kinds of </u><u>bonds </u><u>are present from which we can identify the </u><u>elemental composition</u><u>.</u>
