Across
  1. 2. rainforest nutrient poor soils, canopy structure, very diverse species
  2. 6. buffer between fresh and marine waters, very productive ecosystems
  3. 8. fires, very nutrient rich soils
  4. 10. collection of ecosystems with similar temperatures, rainfall totals,and climax/mature communities
  5. 13. forest seasons, deciduous forests
  6. 15. where rivers meet the sea, sediments/nutrients often dropped from
  7. 16. measurement of the variety and richness of species in an ecosystem
  8. 17. fires, woody trees, wet/dry season
  9. 18. between low and high tide, organisms deal with waves and partial dry times
  10. 20. all the biotic and abiotic components interacting in an area
Down
  1. 1. shelf shallow seas
  2. 3. standing water
  3. 4. vents chemosynthesis supports food chain, pocket ecosystems
  4. 5. biomes Characterized by light and water depth; fresh or saltwater
  5. 6. flowing water
  6. 7. region ocean seafloor, depend on nutrient input from above
  7. 9. zone where light penetrates, photosynthesis
  8. 11. low growth, frozen desert, permafrost
  9. 12. region open water, sparse organisms
  10. 14. zone no light, no photosynthesis, depends on input from above
  11. 19. sparse vegetation, mineral rich soil, biocrust
