A certain species of pine tree survives only in scattered locations at elevations above 2,800 m in the western United States. To understand why this tree grows only in these specific places an ecologist should

#Unit 10. Ecological Principles
  1. Conclude that lower elevations are limiting to the survival of this species.
  2. Study the anatomy and physiology of this species.
  3. Investigate the various biotic and abiotic factors that are unique to high altitude.
  4. Analyze the soils found in the vicinity of these trees, looking for unique chemicals that may support their growth.
