MAKE CONNECTIONS Review the discussion of feedback regulation in Concept 1.1. Could effects of globalwarming on peatlands alter CO2 concentrations in waysthat result in negative or positive feedback? 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)
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.
