This is a very short quiz with no math, mostly for my students but everyone can respond, to find out where our understanding lies so far on carbon balance. These questions are based on the information I have discussed from several past journals about the experiments we are running and carbon balance in general. These questions are also directly related to my journal from May 12, the graphs and the information discussed there. So feel free to check that journal if you need a refresher.
Directions: Observe the graph below and note the change in CO2 over time. Also note the level of CO2 being measured in pm's (parts per million). Remember that this graph represents a certain time of day, so as the day moves on the amount of CO2 will change in response to more plant activity or more decomposer activity. Then answer the following questions:
- How much CO2 is the graph showing?
- What time of day was this data collected?
- In two more hours, when the next sample will be collected, will the amount of CO2 measured move up or down? Why!
Use your heads, talk it out, and remember to tell me why you are giving the answer you are giving. You have one week to reply.
Good Luck!
This graph shows CO2 measured in parts per million.
