GEOGRAPHY AND PLANT LIFE 



Geography and life, partners. Geography the mold into 

 which life has been poured. Ecology. 



Questions to ask concerning each plant: How does it 

 get its food, water, and light? How does it overcome the 

 difficulties of too much or too little water, too much or too 

 little light? What are its devices for cross pollination? 

 For distributing its seeds? For crowding out or living with 

 other plants.
