select the correct answer.\nhow are human activities disturbing carbon dioxide levels and affecting marine life?\na. increased carbon dioxide levels have made the oceans more alkaline.\nb. increased carbon dioxide levels have made the oceans more acidic.\nc. increased carbon dioxide levels have led to the production of more oxygen.\nd. increased carbon dioxide levels have stabilized all ocean ecosystems.
Answer
Answer:
B. Increased carbon dioxide levels have made the oceans more acidic.
Explanation:
Step1: Recall CO2 - ocean reaction
When CO2 dissolves in water, it forms carbonic acid (H2CO3).
Step2: Analyze ocean pH change
Carbonic acid dissociates, releasing hydrogen ions (H+), increasing ocean acidity.
Step3: Evaluate options
A is wrong as it makes oceans acidic not alkaline. C is wrong as CO2 doesn't lead to more O2 production. D is wrong as it disrupts not stabilizes ecosystems.
