Carbon and pH

How is pH and acidity correlated?

• as acidity increases, pH decreases

• as acidity increases, pH increases

• as acidity decreases, pH decreases

• pH causes acidity

If the producer population were to be cut in half, what would happen to rate of photosynthesis?

• decrease

• increase

• stay the same

• false, producers only depend on cellular respiration

If the producer population were to be cut in half, what would happen to amount of CO₂ in ocean/atmosphere?

• decrease

• increase

• stay the same

• will be converted into O₂

Carbon dioxide has always been increasing. Why is that an issue now?

• Human activities have accelerated the increase of carbon dioxide
• The increase in carbon dioxide is a natural occurrence
• Carbon dioxide is not a greenhouse gas
• Carbon dioxide levels have actually been decreasing in recent years

Match the pHs

• antacid tablets (aka TUMS)

• 2

• lemon

• 10.5

• pure water

• 7

• ocean water

• 8.2

An ocean with 94% O₂ saturation and 8.0 pH...

• has many producers and not acidic

• has low producers and not acidic

• has many producers and acidic

• has low producers and acidic
