Which statement best describes the relationship between photosynthesis and cellular respiration? Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.
Photosynthesis is part of the carbon cycle, and cellular respiration is not.
Only plants perform photosynthesis, and only animals perform cellular respiration.
Photosynthesis releases carbon into the atmosphere, and cellular respiration removes carbon from the atmosphere.

Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.

Explanation:

The first option clearly expresses the relationship between photosynthesis and cellular respiration.

Cellular respiration releases carbon back into the atmosphere whereas photosynthesis removes the carbon from the atmosphere.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water.

In cellular respiration, the product of the photosynthesis is used by organisms to produce energy.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
