Answer to Question 1

B

Answer to Question 2

The removal of CO2 from the atmosphere takes place during photosynthesis, as plants consume CO2 to produce green matter. Deforestation increases CO2 in the atmosphere as timber is cut. If forests are burned or left to rot, it then releases CO2 directly into the air, perhaps accounting for about 10 percent of the observed increase.
