How do the processes of respiration, combustion and photosynthesis determine the percentage of carbon dioxide in the atmosphere?

The process of respiration,combustion and photosynthesis determine the percentage of carbon dioxide in the atmosphere as they either take in, give out or use up carbon dioxide for their processes to procede hence, affecting the percentage of carbon dioxide in the atmosphere

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%).

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
