Which of the following statements best describes the effect of climate on biome distribution?

#Unit 10. Ecological Principles
  1. Knowledge of annual temperature and precipitation is sufficient to predict which biome will be found in an area.
  2. Fluctuation of  environmental variables is  not  important if  areas  have  the  same  annual temperature and precipitation means.
