Across
  1. 5. A role an organism plays within an ecosystem e.g. primary producers have a niche role in providing energy to primary consumers
  2. 6. At risk of damage or collapse
  3. 7. Changes caused to ecosystem functioning
  4. 9. Organisms which use the suns energy to create their own food
  5. 11. The situation in which stability is achieved in an ecosystem – through constant change
  6. 12. A measure in the rate of change and impacts on an ecosystem. Catastrophic suggests large changes which are fast
  7. 13. Caused on purpose
  8. 14. The interdependence of species within an ecosystem on one another e.g. within a food web or symbiotic relationships
  9. 17. The rate of recovery to a change in an ecosystem
  10. 19. Caused without intention
  11. 21. The amount of energy to support larger organisms is greater in the trophic level below them. This is shown as a pyramid in a diagram form.
  12. 23. A level of organisms within a food chain determined by how they obtain energy e.g. primary producers are the first trophic level
  13. 24. Able to withstand disturbance or stress
Down
  1. 1. Refers to a threshold level beyond which an ecosystem cannot recover
  2. 2. Organisms which obtain their energy from eating other organisms and are higher on the food chain
  3. 3. The ability of population to maintain its numbers through a stress e.g. wallabies
  4. 4. The degree to which ecosystems meet their prestress level in recovery to a change
  5. 8. A slow rate of change
  6. 10. The differences in the number of species, or genetic variations within a particular population or ecosystem
  7. 14. The factors which determine an ecosystems location and which may cause it to be vulnerable
  8. 15. Nutrients are continually cycled through ecosystems, passing from organism to organism
  9. 16. Organisms within an ecosystem linked together through the passing of energy from one to another
  10. 18. The rate at which biological matter (biomass) is produced by an ecosystem, measured using a rate of energy in a particular space, over time e.g. kj/m2/year
  11. 20. Energy is received in an ecosystem through primary producers and passes to one organism to another and is also lost to the atmosphere as heat
  12. 22. The ability of an ecosystem or organism to resist change e.g. eucalypt trees
  13. 25. The size or shape of an ecosystem
