Hi Mr. Wood its Brittney from 6th period science. I am writing you this to answer the questions on quiz #1. 1. How much CO2 is the graph showing? the amount of co2 the graph is showing is 387.7 pm. 2.What time of day was this data collected? The time of day is 3:20 AM. 3.In two more hours, when the next sample will be collected, will the amount of CO2 measured move up or down? Why! In two more hours the amount of co2 will drop because the plant activity and decomposer activity has decreased. Well thanks for taking the time to read my answers. We all miss you!

Your student, Brittney

Thank you for the answers and the comments. Your thinking is good, but remember that photosynthesis takes in CO2 and decomposers give off CO2.Mr. Wood
