  1. a every cell membrane has a mixed composition of phospolipids
  2. b the range of resources and conditions a species actually uses or can tolerate at optimal efficiency; smaller than fundamental niche
  3. c adaptation that lasts only as long as the individual organisms does (plants in windy places)
  4. d Process that occurs when soils in arid areas are brought under cultivation through irrigation. In arid climates, water evaporates quickly off the ground surface, leaving salty residues that render the soil infertile.
