- 2. Ability of an animal to look like another more harmful animal
- 3. Succession ecological sucession begins in a lifeless area with no soil
- 4. an organism that needs to get its own food by eating another organism.
- 6. Community The final stage of succession. A stable community in an ecosystem that no longer goes through major ecological changes. It consists of dominant species of plants and animals.
- 7. Chain A series of steps in which organisms transfer energy by eating and being eaten.
- 9. The study of the relationships between organisms and their environment.
- 12. factor A non-living part of the environment.
- 14. The place an organism lives.
- 15. An organism that the feeds on the bodies of dead animals.
- 17. independent factors limiting factor that affects all populations in similar ways, regardless of population size
- 20. factors The resources that organisms need to survive. When unavailable these factors limit a populations' ability to grow/increase.
- 23. A close relationship between two organisms in which they both benefit/help each other
- 24. Includes all the air, land, and water where life exists.
- 26. dependent factors limiting factor that depends on population size
- 27. An organism that feeds on a living host
- 29. Web Consists of many overlapping food chains in an ecosystem.
- 30. An organism that can not make it's own food and must eat another organism.
- 31. Living organisms interacting with each other and their nonliving environment.
- 36. Capacity Largest number of individuals of a population that a environment can support
- 38. An animal that hunts other animals for food
- 39. An organism that makes it's own food, usually using sunlight by a process called photosynthesis.
- 40. Any feature an organism has to help it survive in its' environment.
- 44. growth Population growth that is unhindered because of the abundance of resources for an ever-increasing population.
- 45. is an organism's role (job) within its' community.
- 46. A large region that has a specific type of climate and certain types of plant and animal communities
