Across
  1. 2. active at dawn or dusk
  2. 5. Tree stratum, small trees and saplings, shrub, herb, and ground are the five zones of this biome
  3. 7. organism that feeds entirely on producers
  4. 9. this population is an example of the founder effect; the original settlement of this population had an unusually high number of genes for polydactylism in its gene pool
  5. 10. Biome found in small areas surrounded by other biomes, hot dry summers and cool wet winters, nutrient poor soil,lots of shrubs and lots of biodiversity. Adaptations in this biome include plants adapted to wildfires, birds that are ground dwellers, and animals of all types that are nocturnal or crepuscular
  6. 12. an organism that must ingest other organisms to obtain energy because it does not have the capability of producing its own energy
  7. 13. a change is the frequency of a gene’s occurence in a population; most noticable in smaller populations; two examples of this are founders effect and bottle-neck events
  8. 15. type of succession that occurs when no is present
  9. 16. Convention on International Trade in Endangered Species of Wild Fauna and Flora; a treaty signed in 1973 to regulate the international trade of plant and animal species
  10. 19. organism that feeds on primary consumers
  11. 20. a federal regulatory agency tasked with the protection of the environment
  12. 22. behavior occurring in small populations that leads to a reduction in genetic variation and therefore an increase in disease and infertility
  13. 24. an act signed in 1900 that made it illegal to buy or sell plants or animals that were acquired illegally
  14. 25. the only marsupial found in North America
  15. 26. when water vapor is converted from a gas to a liquid
  16. 27. an event such as a natural disaster, over hunting, or habitat destruction that leads to a significant reduction in the population of a species
Down
  1. 1. A high energy molecule created during photosynthesis that allows for storage of energy that can later be converted through respiration to ATP
  2. 3. organism that feeds on primary and secondary consumers
  3. 4. a grassland animal similar to an ostrich with long powerful legs that allow them to travel fast and move in a zig-zag pattern
  4. 6. any liquid or frozen water that falls from the atmosphere and returns to the Earth
  5. 8. this type of population distribution occurs when organisms are fairly evenly spaced and distributed due to competition for resources or territorial behavior
  6. 11. first organisms that can colonize during primary succession
  7. 14. when water is converted from a liquid to a gas
  8. 17. A testable explanation for an observed phenomenon; one of the major distinctions of modern day science is the testability of these explanations
  9. 18. an organism that produces its own energy
  10. 21. type of succession that occurs when a disaster has disturbed the living things of an area but the soil is still present
  11. 23. active at night
