Textbook Question
Chapter 56.4, Problem 2CC
MAKE CONNECTIONS → There are vast stores of organic matter in the soils of northern coniferous forests and tundra around the world. Suggest an explanation for why scientists who study global warming are closely monitoring these stores (see Figure 55.14).

MAKE CONNECTIONS Describe the relationship between pH andacidity. (See Concept 3.3.) Overall, is the precipitation in this forest becomingmore acidic or less acidic?
MAKE CONNECTIONS Refer to the discussion of oceanacidification in Concept 3.3. Ocean acidification andchanges in the distribution of C3 and C4 plants may seemto be two very different problems, but what do theyhave in common? Explain.
MAKE CONNECTIONS As noted in Figure 52.15, theaddition of nutrients to a lake can cause an algal bloom.When these algae die, complex molecules in their bodiesare broken down by decomposers using aerobic respiration. Explain why this would reduce the lake’s oxygenlevels (see Concept 9.1)
