Ecology: Populations Vocabulary 1. Population growth – Change in population size with time. 2. Exponential growth – The number of organisms increase by an ever increasing rate. 3. Carrying capacity – The number of organisms (population) an area can support over time. 4. Density-dependent factors – Environmental factors, such as disease and competition for food, that limit population growth. 5. Density-independent factors – Environmental factors, mostly weather, storms, floods, etc., that limit population growth. 6. Predation – Predator/prey relationships. 7. Population growth rate – Difference between birth and death rates. 8. Immigration – Movement of individuals into a population. 9. Emigration – Movement of individuals out of a population. 10. Natural resources – Any part of the environment used by humans for their benefit. 11. Renewable – Can be re-grown, recycled, or replenished. 12. Non-renewable – Not replaced/recycled naturally. 13. Extinction – End of existence of a species. 14. Threatened species – Rapidly declining species. 15. Endangered species – The number of species becomes really low. 16. Pollution – The contamination of any part of the environment by excess waste material. 17. Biodegradable – Can be broken down by natural processes. 18. Non-biodegradable – Cannot be broken down by natural processes. 19. Preservation – The act of keeping an area/organism from harm/destruction. 20. Conservation – Planned management of an area to prevent exploration or destruction. Name _________________________________ Ecology: Populations Vocabulary Test A. B. C. D. E.
