Carbon Balance in Warming and Drying Tundra

Hi Mr. Wood. This is Brandon G. from your 6th period class. Answers to the Quiz Questions

1.The co2 is 385-388 parts per million

  1. The data was collected in the late afternoon/evening

  2. In 2 more hours, there would be less carbon dioxide at night because there is no sunlight and the plants would have already used the co2 in that morning

    I hope I got them right! :)

Thanks for the answers. Good thinking, but remember that during photosynthesis the plants are using more CO2 and giving off oxygen. At night the plants stop photosynthesis but the decomposition in the ground continues to give off CO2, so there should be more at night.Mr. Wood
