Final answer:
The anthropogenic release of carbon is primarily from the terrestrial pool (including sources like fossil fuels) to the atmospheric pool, as carbon dioxide is released through activities such as the burning of fossil fuels.
Step-by-step explanation:
The student's question about the anthropogenic release of carbon asks which pools carbon is being transferred between. The correct answer is c. terrestrial; atmospheric. This is because human activities, such as the burning of fossil fuels and deforestation, release carbon from the terrestrial sources (e.g., coal, oil, gas) into the atmosphere in the form of carbon dioxide. This release of carbon dioxide is much faster than the rate at which it can be absorbed by photosynthetic organisms or dissolved in the ocean.
