Question
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.

Answer
The correct statement about the carbon cycle is:"Today the amount of
in the atmosphere is increasing because the ocean and plants currently absorb about half of the
from human activities."Explanation:- Three hundred years ago, the carbon cycle was more balanced, with the amount of
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.- The removal of
gas from the atmosphere does not result in increased global temperatures; rather, an increase in
levels contributes to global warming.- Today, more
is entering the atmosphere than is being removed, primarily due to human activities.- Burning forests releases
into the air, contributing to higher atmospheric
levels.- Three hundred years ago, human activity contributed much less to atmospheric
compared to today.
