Which holds the majority of CO2?
A. vegetation
B. animals
C. phytoplankton
D. seawater
E. the atmosphere
Answer (2)
Seawater holds the majority of CO2 compared to vegetation, animals, and the atmosphere, absorbing about 30% of atmospheric CO2. Its ability to dissolve and store CO2 makes it a crucial part of the carbon cycle. Therefore, the correct answer is seawater .

Seawater holds the majority of CO2 compared to vegetation, animals, phytoplankton, and the atmosphere. Approximately 30% of atmospheric CO2 is absorbed by oceans, which have a significant CO2 storage capacity. Thus, while other components participate in the carbon cycle, the oceans store the most carbon dioxide. ;
