1. Ecology: Scientific study of interactions among organisms and between organisms and their environment
2. Biosphere: Part of Earth in which life exists including land,water and air or atmosphere
3. Species: Group of similar organisms that can breed and produce fertile offspring
4. Population: Group of individuals of the same species that live in the same area
5. Community: Assemblage of different populations that live together in a defined area
6. Ecosystem: Collection of all organisms that live in a particular place,together with there nonliving environment
7. Biome: Group of ecosystems that have the same climate and dominant communities
8. Autotroph: Organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer
9. Heterotroph: Organism that obtains energy from the foods it consumes;also called a consumer
10. Producer: Organism that can capture energy from sunlight or chemicals and use it to produce food from inorganic compounds;also called a autotroph
11. Photosynthesis: Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches
12. Chemosythesis: Process by which some organisms such as certain bacteria, use chemical energy to produce carbohydrates
13. Consumer: Organism that relies on other organisms for its energy and food supply; also called a hetrotroph
14. Herbivore: Organism that obtains energy by eating only plants
15. Carnivore: Organism that obtains energy by eating animals
16. Omnivore: Organism that obtains energy by eating both plants and animals
17. Detrivore: Organism that feeds on plants and animal remains and other dead matter
18. Decomposer: Organism that breaks down and obtains energy from dead organic matter
19. Food Chain: Series of steps in an ecosystem in which organisms transfer energy by eating and being eaten
20. Food Web: Network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem
21. Trophic Level: Step in a food chain or food web
22. Ecological Pyramid: Diagram that shows relative amounts of energy or matter within each trophic level in a food chain or food web
23. Biomass: Total amount of living tissue within a given trophic level
24. Niche: Full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions
25. Habitat: The area where an organism lives, including the biotic and abiotic factors that affect it
26. Resource: Any necessity of life such as water, nutrients,light,food, or space.
27. Competitive Exclusion Principle: Ecological rule that states that no two species can occupy the same exact niche in the same habitat at the same time
28. Predation: Interaction in which one organism captures and feeds on another organism
29. Symbiosis: Relationship in which two species live closely together
30. Mutualism: Symbiotic relationship in which both species benefit from the relationship
31. Commensalism: Symbiotic relationship in which one member of the association benefits and the other is neither helped nor harmed
32. Parasitism: Symbiotic relationship in which one organism lives in or on another organism (the host) and consequently harms it
33. Predator: an animal that naturally preys on others
34. Prey: An animal hunted or killed by another for food
35. Predator-Prey Relationship: Mechanism of population control in which a population is regulated by predation
