Across
- 4. All of the populations of organisms that live in an area at the same time
- 5. is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor
- 7. an organism that eats both plants and animals
- 9. The community plus the environment
- 11. is all of the food chains in an ecosystem.
- 12. a type of symbiosis where one organism benefits and the other is harmed
- 13. The movement of water through the subsurface soil layers, usually continuing downward to groundwater. It is a part of the water cycle
- 15. is the process of water movement through a plant and its evaporation from leaves, stems and flowers; part of the water cycle
- 18. the place where a particular organism lives within its environment
- 19. the sequence of transfers of matter and energy in the form of food from organism to organism.
- 21. occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds.
- 22. large land habitats characterized by distinctive kind of dominant vegetation, temperature and precipitation determine types
- 23. nonliving portion of the environment, factors such as moisture, temperature, soil
- 24. A group of organisms that are genetically similar enough to interbreed and produce fertile offspring.
- 27. organisms that eat primary consumers for energy, secondary consumers can either be carnivores or omnivores
Down
- 1. all of the organisms of one species that live in the same area, at the same time
- 2. a type of symbiosis where one organism benefits and there is no effect on the other
- 3. interaction between two different organisms living in close physical association
- 6. is when water being held in the atmosphere falls to the earth as rain, sleet, hail, and snow. Precipitation is part of the water cycle.
- 8. a global ecosystem composed of living organisms (biotic) and the nonliving (abiotic factors) from which they derive energy and nutrients
- 10. is the process by which water changes from a liquid to a gas or vapor, part of the water cycle
- 14. a type of symbiosis where both organisms benefit
- 16. Where and how an organism obtains its food, all of the special requirements defining its role
- 17. another term for herbivore
- 20. the type of organism needed to keep minerals cycling back into the ecosystem
- 25. includes all photosynthetic organisms
- 26. a graphical representation of basic climatic parameters, that is monthly average temperature and precipitation, at a certain location
