Gaseous carbon dioxide (co 2 ) is the most abundant form of carbon in the atmosphere, where it occurs in a concentration of about 400 ppm (0.04%), although methane (ch 4 , 1.8 ppm) is also significant. In doing so, it explores the following key questions: Section 2.1 energy flow in ecosystems cloze activity energy flow page 16 1. Each of these questions provides four or five options, from which you need to select the correct answer. {2.2, 2.3} what are the implications for transitions. Key aspects of the global carbon cycle are presented in figure 5.3 (see also chapter 17 and figure 17.1).

Carbon farming is being promoted as agriculture’s answer to climate change. {2.2, 2.3, 2.4, 2.6} to what extent do 1.5°c pathways involve overshooting and returning below 1.5°c during the 21st century? C chapter 2 energy flow and nutrient cycles support life in ecosystems. Gaseous carbon dioxide (co 2 ) is the most abundant form of carbon in the atmosphere, where it occurs in a concentration of about 400 ppm (0.04%), although methane (ch 4 , 1.8 ppm) is also significant.
