Read the following passage and answer the questions(51 – 54)[ 4 x 0.5 =2]           Of the GHGs, CO2 is of greatest concern because it contributes the most to the Enhanced Greenhouse Effect and climate change. For this reason, scientists have been studying this molecule carefully and attempting to quantify its abundance in the atmosphere and track how and why it changes. The CO2 molecule is involved in a complex series of processes called the carbon cycle, where the carbon atom within the molecule moves between many different natural reservoirs. As carbon is transferred between reservoirs, processes which release CO2 into the atmosphere are called sources, and processes which remove CO2 from the atmosphere are called sinks. .
