Across
  1. 2. -species way of life
  2. 5. -natural selection that can lead to natural selection
  3. 9. efficiency – percent of usable chemical energy transferred as biomass.
  4. 11. species- have a large effect on the types and abundance of other species
  5. 12. species- occupy narrow niche
  6. 13. -large regions such as forest, desert, and grasslands with distinct climates and certain species adapted to them.
  7. 15. – the amount or mass of living organic material
  8. 16. surrounded by membrane and has a distinct nucleus
  9. 18. web – complex network of interconnected food chain
  10. 19. make the nutrient they need from compounds and energy obtained from the environment
  11. 22. – everything around us includes living and non-living things.
  12. 24. is also surrounded by a membrane but it has no distinct nucleus and no other internal parts surrounded by membrane
  13. 26. extinction- species have disappeared at low rate
  14. 28. species- species that are found in only one area.
Down
  1. 1. species- another term for non- native species
  2. 3. evolution – the process whereby earths life changes overtime through changes in the genes population
  3. 4. species – have a broad niche
  4. 6. diversity- population vary slightly in their genetic make-up
  5. 7. -random changes in the structure or number of DNA molecule in a cell that can be inherited by the offsprings
  6. 8. diversity- the number of different species it contains combined with the relative abundance within those species
  7. 9. an entire species cease to exists
  8. 10. – consist of the earths air, water and soil where life is formed.
  9. 14. – temporary storage sites
  10. 17. can convert simple organic compounds from their environment into ore complex nutrient compounds
  11. 20. -group of individuals of the same species that live in the same place at the same time.
  12. 21. using a resource over and over in the same form
  13. 23. species- plays a major role in shaping communities by creating and enhancing their habitat in ways benefit other species.
  14. 25. -the biological that studies how organism interact with their environment.
  15. 27. – the natural force that tends to cause physical things to move towards each other.
