Press the hotspot for where you would find glucose (sugar made in photosynthesis).

Why are photosynthesis and cellular respiration called complementary reactions?

*HINT: The same molecules are in both of them .

• Photosynthesis can only happen after cellular respiration.

• Only plants do photosynthesis, and only animals do cellular respiration.

• Each process uses what the other process produces.

Which process in the carbon cycle traps carbon for long periods of time?

*HINT: where does carbon stay the longest?

• photosynthesis

• formation of fossil fuels

• cellular respiration

Which statement correctly describes the relationship between fossil fuels, carbon dioxide, and global warming?

• Burning fossil fuels releases carbon dioxide. Excess carbon dioxide causes global warming.

• Carbon dioxide produces fossil fuels. Fossil fuels prevent global warming.

• Global warming creates fossil fuels. Fossil fuels absorb carbon dioxide.

How is global warming related to climate change?

• Global warming and climate change mean the same thing.

• Global warming is one factor that leads to climate change.

• Climate change is one factor that prevents global warming.

Which of these is most likely to occur along with climate change?

• more polar ice

• changes in precipitation patterns

• more kinds of organisms on Earth
