Chemistry Cluster #1

Please refer to Passage 1 to answer the following question:

Which claim about the kelp carbon pool is best supported by evidence from the information and the model above?

Please refer to Passage 1 to answer the following question:

Which statement uses the model to describe how kelp contributes to a reduction of carbon entering the atmosphere?

Please refer to Passage 1 to answer the following question:

Which model identifies the process that converts light energy into chemical energy inside the

kelp?

Please refer to Passage 2 to answer the following question:

If the trend in atmospheric CO₂ levels continues, sea urchin populations may be impacted.

Describe evidence from the graph that supports this claim. 

Please refer to Passage 3 to answer the following question:

As atmospheric CO₂ levels increase, more CO₂ dissolves in ocean water and forms carbonic acid (H₂CO₃).

Explain how this process affects the availability of carbonate ions (CO₃²⁻) in seawater and describe the resulting impact on the ability of sea urchins to form calcium carbonate (CaCO₃) shells.
