Final answer:
After being in the atmosphere, carbon dioxide can be absorbed by bodies of water, taken up by plants, or released back into the atmosphere through various processes. The highest CO₂ emissions are associated with human activities, particularly the burning of fossil fuels.
Step-by-step explanation:
After being in the atmosphere, carbon dioxide (CO₂) can go several different places. It can be absorbed by bodies of water, such as oceans and lakes, through a process called carbon sequestration. It can also be taken up by plants through photosynthesis, where it is converted into carbohydrates and other organic compounds. In addition, some CO₂ can be released back into the atmosphere through processes like respiration, decomposition, and combustion.
The highest CO₂ emissions are typically associated with human activities, particularly the burning of fossil fuels such as coal, oil, and natural gas. These activities release large amounts of CO₂ into the atmosphere, contributing to the current rise in atmospheric CO₂ levels and the enhanced greenhouse effect.
