Hi Mr.Wood,

It is Fiona Daniels from your second period class. Here all the answers for the quiz

How much CO2 is the graph showing? I think the the CO2 graph is showing 386.

What time of day was this data collected?

The time of day that this data was collected was the first thing in the morning which was 2:56am

In two more hours, when the next sample will be collected, will the amount of CO2 measured move up or down? Why!

It would move up because of the oxygen in the air and the carbon dioxide.

From,

Fiona Daniels

Thank you for the answers. Good thinking, but remember that as we give of CO2 while we breath, the plants take that in and give off oxygen.Mr. Wood
