Ecology
Across
- 7. Organisms that can interbreed and produce fertile young
- 8. When both species benefit from a relationship
- 9. A species which indicates how healthy an ecosystem is
- 12. A trait that helps an organism survive and reproduce
- 18. Succession that occurs on surfaces where no soil exists
- 19. Any biotic or abiotic factor that restricts the existence, numbers, reproduction, or distribution of organisms
- 20. A species whose numbers are so small that the species is at risk of extinction
- 21. Non-living factors in an environment
- 22. All the biotic and abiotic factors in a particular area
- 24. When population growth hovers around the carrying capacity
- 25. How an organism lives, finds its food, find its mate, build and maintains its home, along with the role it plays within its ecosystem
Down
- 1. First species, such as lichen, to populate an area during primary succession
- 2. When one species benefits while the other species is harmed
- 3. Largest number of individuals of a population that an environment can support
- 4. When populations begin growing faster as they grow larger
- 5. One species living in a particular area
- 6. Occurs when species share the same resources
- 10. A process in which individuals with traits that help them survive and reproduce better pass on those traits so that, over time, those traits become more common within a population
- 11. The variety of life in the world or within a particular ecosystem
- 13. A species that has an unusually large effect on its ecosystem
- 14. Succession following a disturbance that destroys a community without destroying the soil
- 15. Just the biotic factors or all the populations within an ecosystem
- 16. Living factors in an environment
- 17. When one species benefits but the other neither benefits nor is harmed
- 23. A change in a population over time
