Figure 54. 1: how are the components in figure 54. 1 linked by the flow of energy, when primary producers expend energy to build new tissue, this is ________, net primary productivity, the amount of energy available to consumers. 1: maintenance costs, both a and b, both b and c, which of the following consume other living organisms, primary producers, herbivores, carnivores, decomposers, both b and c. 2,640,000 kcal/m2, what is the overall gross photosynthetic efficiency: 0. 01, 0. 1, 1, 100, plants never use 100% of the incoming solar radiation for photosynthesis on a yearly basis. What is a reasonable explanation for this: plants cannot photosynthesize during winter (in cold winter climates), plants cannot photosynthesize during dry periods. 5: the pigments that drive photosynthesis respond to only a fraction of the wavelengths available, both a and c, both b and c. Earth"s climate: carbon can be recycled only a limited number of times.
