Populations
Across
- 2. factors factors that can impact a population regardless of its density such as weather, natural disasters and human activity
- 5. a po;ulation begins with a period of slow growth followed by a period of exponential growth before leveling off at a stable size indicated by an s-shaped curved
- 7. the variety of species within an ecosystem
- 8. the ability of an ecosystem to resist change from a disturbance
- 10. factors are factors that are affected by the number of individuals in the area such as competition, predation, parasitism and disease
- 12. the ability of an ecosystem to recover after it has undergone an disturbance
- 14. population size increases in a relatively short time indicated with a j-shaped graph
- 15. the sequence of biotic changes that restore a damaged community
Down
- 1. two organisms compete for the same resources
- 3. a space that contains all the physical, chemical, and biological factors that a species needs to survive and reproduce
- 4. a close ecological relationship between two or more organisms such as mutualism, commensalism and parasitism
- 6. all the biotic and abiotic factors in an environment where an organism lives
- 9. process by which one organism captures and feeds upon another organism
- 11. simplified diagram that shows the number of surviving individuals over time from a measured set of births
- 13. the maximum population of a species that a particular environment can normally and consistently support
