Ecosystem Resilience & Vulnerability Crossword
Across
- 5. A role an organism plays within an ecosystem e.g. primary producers have a niche role in providing energy to primary consumers
- 6. At risk of damage or collapse
- 7. Changes caused to ecosystem functioning
- 9. Organisms which use the suns energy to create their own food
- 11. The situation in which stability is achieved in an ecosystem – through constant change
- 12. A measure in the rate of change and impacts on an ecosystem. Catastrophic suggests large changes which are fast
- 13. Caused on purpose
- 14. The interdependence of species within an ecosystem on one another e.g. within a food web or symbiotic relationships
- 17. The rate of recovery to a change in an ecosystem
- 19. Caused without intention
- 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.
- 23. A level of organisms within a food chain determined by how they obtain energy e.g. primary producers are the first trophic level
- 24. Able to withstand disturbance or stress
Down
- 1. Refers to a threshold level beyond which an ecosystem cannot recover
- 2. Organisms which obtain their energy from eating other organisms and are higher on the food chain
- 3. The ability of population to maintain its numbers through a stress e.g. wallabies
- 4. The degree to which ecosystems meet their prestress level in recovery to a change
- 8. A slow rate of change
- 10. The differences in the number of species, or genetic variations within a particular population or ecosystem
- 14. The factors which determine an ecosystems location and which may cause it to be vulnerable
- 15. Nutrients are continually cycled through ecosystems, passing from organism to organism
- 16. Organisms within an ecosystem linked together through the passing of energy from one to another
- 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
- 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
- 22. The ability of an ecosystem or organism to resist change e.g. eucalypt trees
- 25. The size or shape of an ecosystem
