Population and Community Ecology
Across
- 1. the quantitative study of populations
- 3. dispersion type that is caused by uneven distribution of resources
- 8. networks of populations that can exchange individuals
- 10. Individuals must maintain a steady-state internal environment regardless of external environment
- 11. Number of species
- 12. Niche is subdivided to prevent competition
- 15. a group of association of populations of two or more different species that are occupying the same geographical area at the same time
- 16. The actual niche space an organism occupies
- 17. a species that has a disproportionate effect on the habitat/ecosystem
- 19. the upper limit of resources of a habitat that can support a population
- 21. number of organisms per unit of area
- 22. type of symbiosis where one partner benefits and the other is not affected positively or negatively
- 25. average interval between birth of an individual and birth of its offspring
- 26. study of how organisms relate to one another and their environment
- 27. leads to evolutionary adaptation in response to environmental change
Down
- 2. groups of individuals in the same space at the same time
- 4. type of symbiosis where both partners benefit
- 5. one example of a density dependent factor
- 6. All the niche space an organism COULD use
- 7. type of parasite that lays eggs in a live host
- 9. how evenly distributed the species are
- 13. number of offspring produced in a standard time
- 14. death rate in a standard time
- 18. the total of all the ways an organism uses the resources of its environment
- 20. a bat eating a fruit and depositing the seed elsewhere is an example of
- 23. bird migration is what type of response to changing environmental conditions
- 24. population geographic distribution
