The following graph is the outcome of a computer model simulating what happens under climate and atmospheric change in a conifer plantation forest. How can its results be explained?
Question 9 options:
1) The combined effect of increased CO2 and increased temperature reduce NPP
2) Stemwood volume increases over time with increasing temperatures because of increased photosynthetic rates
3) Stemwood volume increases over time when the fertilization effect of CO2 reduces the water stress caused by the increase in temperature.
4) Increasing temperature has always a negative effect on NPP because it increases heterotrophic respiration dramatically
QUESTION 9 The results can be explained as; 4) Increasing... View the full answer
