Answer: B. Increased human conservation activities.
-Overexploitation means harvesting species from the wild at rates faster than natural populations can recover. Overfishing and overhunting are both types of overexploitation.

The correct answer is D. Flask 3 (only). This is because fish produce carbon dioxide products of cellular respiration and they do not undergo photosynthesis therefore not consuming carbon dioxide.
This is where cellular respiration is being involved.

Catabolic reactions is involved in cellular respiration where large molecules are broken to small molecules so as to release energy.
