If you conclude that vegetation at every point on Earth exactly resembles the predicted biome distribution in a climograph, then ________.

#Unit 9. Diversity of Life Forms
  1. you are ignoring human land use changes or impacts, which have highly altered many regions within biomes
  2. the biome spanning the smallest combined ranges in precipitation and temperature is the tundra
  3. the biome most sensitive (in danger) from global warming is the desert
  4. you are ignoring the fact that local differences in soil, elevation, or topography can result in considerably different plant communities that are embedded within named biomes

a. The reaction is both enthalpically and entropically opposed. It is nonspontaneous (endergonic) at all temperatures.

2.

 −

− 

b. The reaction is enthalpically opposed (endothermic) but entropically favored. It is spontaneous only at temperatures above T = ΔH/ΔS.
