Across
  1. 4. The type of farming where animals are grown in a temperature-controlled environment where their movement is limited, so they waste little energy keeping warm or moving
  2. 5. An animal that hunts and kills other animals
  3. 6. A measure of how common or rare a particular organism is in a given environment
  4. 9. The cycling of carbon through the living and non-living world
  5. 10. An organism that can survive and reproduce in extreme conditions
  6. 12. The amount of biological material in an organism
  7. 13. A measure of the variety of all the different species of organisms on Earth
  8. 14. A measured line or area along which ecological measurements are made
  9. 17. The organization of living organisms into groups according to their similarities
  10. 18. Microorganisms that break down waste products and dead bodies
  11. 20. Feeding levels in an ecosystem
  12. 24. A non-living factor of the environment
  13. 25. A group of organisms that can breed together and produce fertile offspring
  14. 26. records the numbers of organisms rather than just the type
  15. 28. A living factor of the environment
  16. 32. An animal that is hunted and killed by another animal
  17. 33. A limit on the number and size of fish that can be caught in a certain area
  18. 34. Model of feeding relationships based on the biomass of organisms at each level of a food chain
  19. 36. The cutting down of forests (large areas of trees)
Down
  1. 1. The permanent loss of all members of a species from an area or the world
  2. 2. having enough food to feed the population
  3. 3. Special features that make an organism particularly well suited to the environment where it lives
  4. 7. A change in things like temperature or weather patterns in a part of the world or across the whole world
  5. 8. Where particular types of organisms are found within an environment
  6. 11. When gases in the atmosphere absorb energy radiated by the Earth and re-radiate it back towards the Earth, helping to keep it warm
  7. 15. The process by which living organisms compete with each other for limited resources such as food, light or reproductive partners
  8. 16. The interaction of a community of living organisms with the abiotic parts of their environment
  9. 19. The network of relationships between different organisms within a community, e.g. each species depends on other species for food, shelter, pollination, seed dispersal etc.
  10. 21. The place where organisms live
  11. 22. Animals that eat primary consumers
  12. 23. Group of interdependent living organisms in an ecosystem
  13. 27. Model of feeding relationships based on the number of organisms at each level of a food chain
  14. 29. The rise in the average global temperature
  15. 30. Animals that eat producers
  16. 31. Organisms such as plants and algae that can make food from raw materials such as carbon dioxide and water
  17. 35. A sample area used for measuring the abundance and distribution of organisms in the field
