Which of the following is correct about the carbon cycle? Three hundred years ago.the amount of CO_(2) flowing into the atmosphere was equal to the amount flowing out of the atmosphere. Today the amount of CO_(2) in the atmosphere is increasing because the ocean and plants currently absorb about half of the CO_(2) from human activities. The removal of CO_(2) gas from the atmosphere resulted in increased global temperature since 1980. Today more CO_(2) is coming out of the atmosphere than is going into the atmosphere. Today burning forests reduces the amount of CO_(2) gas released into the air. Three hundred years ago human activity contributed to a large amount of CO_(2) flowing into the atmosphere.

The correct statement about the carbon cycle is:<br /><br />"Today the amount of \(CO_2\) in the atmosphere is increasing because the ocean and plants currently absorb about half of the \(CO_2\) from human activities."<br /><br />Explanation:<br />- Three hundred years ago, the carbon cycle was more balanced, with the amount of \(CO_2\) flowing into the atmosphere roughly equal to the amount flowing out. However, human activities such as burning fossil fuels and deforestation have disrupted this balance.<br />- The removal of \(CO_2\) gas from the atmosphere does not result in increased global temperatures; rather, an increase in \(CO_2\) levels contributes to global warming.<br />- Today, more \(CO_2\) is entering the atmosphere than is being removed, primarily due to human activities.<br />- Burning forests releases \(CO_2\) into the air, contributing to higher atmospheric \(CO_2\) levels.<br />- Three hundred years ago, human activity contributed much less to atmospheric \(CO_2\) compared to today.
