Question

How would the carbon cycle be disrupted if human activities released an extremely large amount of carbon dioxide into the atmosphere?

a
Plants would have more difficulty engaging in photosynthesis, and a massive amount would die off.
b
Plants and animals in Earth's oceans would have more difficulty processing carbon dioxide, and carbonification would not occur in deep marine soils.
c
Animals would have more difficulty breathing, and it would be years before the air contained a healthy amount of oxygen.
d
Humans would have difficulty burning wood and fossil fuels, and it would take years before the air contained a healthy amount of bicarbonate (HCO3-).

Answer 1

b
Plants and animals in Earth's oceans would have more difficulty processing carbon dioxide, and carbonification would not occur in deep marine soils.
