Across
  1. 1. used when you suspect a factor is affecting distribution and sample at regular intervals along it
  2. 3. a feature which allows an organism to survive, compete and be successful in their habitats
  3. 5. competition within a species
  4. 7. a product of combustion
  5. 10. organisms that can survive and reproduce in very extreme environments and can survive conditions that would kill most other organisms e.g hot spring bacteria
  6. 13. a cycle. Present in every living thing. Essential for life.
  7. 14. made up of a community of organisms interacting with the non-living things in their environment
  8. 15. a different cycle consisting of processes like evaporation, transpiration etc.
  9. 16. carbon dioxide + water -> glucose + oxygen
  10. 17. the non-living factors
  11. 21. used to find out quantitive data
  12. 22. all of the organisms of a species in an area
  13. 23. glucose + oxygen -> carbon dioxide + water
  14. 27. removal of trees on a large scale
  15. 28. used to help crops grow
  16. 30. competition between separate species
  17. 32. consumer the animals that eat the p_____ consumers
  18. 34. where rubbish is buried
  19. 36. made up of populations of different species that are all interdependent in a habitat.
  20. 37. photosynthetic organisms such as plats and algae that produce most of the biomass for life on earth
  21. 38. the number of organisms in an ecosystem
  22. 40. sun heats earth surface heating up water and turning it to gas
  23. 41. trapped gases in the earths atmoshphere cause this (6,7)
  24. 42. consumers he animals that eat the s_______ consumers
  25. 44. when each species depends on another within a community. if one species is removed it can affect the whole community
  26. 45. where organisms are found with an ecosystem
Down
  1. 2. loss of water vapour from animals
  2. 4. loss of water vapour from plants
  3. 6. moist air cooling down
  4. 8. another cycle consisting of eating organisms, excretion, photosynthesis etc.
  5. 9. sweating or not sweating, producing toxins, lowering metabolic rate during hibernation etc. (adaptation category)
  6. 11. produced by cattle an rice fields
  7. 12. water trickles through gaps in soil and rocks
  8. 18. caused by harmful toxins/chemicals in the atmosphere condensing in water. destroys limestone (4,4)
  9. 19. food chains and webs show the flow of what?
  10. 20. huddling together, active a night when it is cooler (adaptation category)
  11. 24. they compete for food, territory, water, shelter and mates
  12. 25. a form of waste water from households and businesses etc.
  13. 26. rain, snow or hail
  14. 29. fossil fuel or wood + oxygen -> carbon dioxide + water
  15. 31. warning or camouflage colours, large feet, sharp talons or teeth etc. (adaptation category)
  16. 33. they compete for light, space, water and minerals
  17. 35. introducing products to the environment which have harmful effects
  18. 37. consumer the animals that eat the p________
  19. 39. the living factors
  20. 43. plant material that cannot decay completely and holds large amounts of carbon (4,3)
