Across
  1. 2. used to find species which may be within an area of grass, generally only suitable for small crawling invertibrates
  2. 4. we use this to measure temperature
  3. 5. eats only animal material
  4. 6. competition between members of different species
  5. 8. eats only plant material
  6. 10. obtains energy by eating another organism
  7. 12. the role an organism has in its ecosystem
  8. 15. site of photosynthesis
  9. 19. we use this to measure soil moisture level
  10. 23. the place where an organism lives
  11. 25. all the species living in the habitat along with all non-living factors
  12. 28. can occur when errors in genetic material arise through the mutation process
  13. 29. we use arrows to represent this in a food chain
  14. 32. glucose produced in photosynthesis can be turned into
  15. 34. competition between members of the same species
  16. 35. a group f organisms that can interbreed to produce fertile offspring
  17. 36. name of green pigment that captures light energy
  18. 37. the name of the first stage of photosynthesis
  19. 38. we use this to measure light intensity
  20. 39. the ultimate source of energy for an ecosystem
Down
  1. 1. the factor that acts on members of a population and results in predatation
  2. 3. species that indicate the level of pollution
  3. 7. a group of a single species
  4. 9. sprayed too kill of pests
  5. 11. the only form of nitrogen a plant can absorb
  6. 13. living factors
  7. 14. type of crop which have genes that allow them to grow bigger, stronger and pest resistant
  8. 16. all the different species living together
  9. 17. an organism which makes its own food through photosynthesis
  10. 18. eats both plant and animal material
  11. 20. this occurs when animals need the same resource when in short supply
  12. 21. thick layer that blocks out sunlight from rivers
  13. 22. non-living factors
  14. 24. survival of an organisms variation which makes them better adapted to their environment
  15. 26. the name of the second stage of photosynthesis
  16. 27. used to find the rough number of plants on a small area of ground
  17. 30. a random event that cause changes to the genetic information of an organism
  18. 31. enhance minerals in the soil and improve the growth of the crop
  19. 33. the term used to describe the formation of two or more species from the original species
