Enviromental Science

1. Population - all the inhabitants of a particular town, area, or country.
2. Community - a group of people living in the same place or having a particular characteristic in common.
3. Producer - Beginning of ecosystem that supports consumers
4. Autotroph - an organism that can form nutritional organic substances from simple inorganic substances such as carbon dioxide.
5. Consumer - An organism in the ecosystem that will either feed on other organisms or producers
6. Heterotroph - an organism deriving its nutritional requirements from complex organic substances.
7. Herbivore - an animal that eats only plants
8. Carnivore - an animal that feeds on flesh.
9. Omnivore - an animal or person that eats food of both plant and animal origin.
   10. Decomposer - an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
   11. Biomass - the total mass of organisms in a given area or volume.
   12. Limiting factors -anything that constrains a population's size and slows or stops it from growing
   13. Food web - consists of all the food chains in a single ecosystem
   14. Food chain - a hierarchical series of organisms each dependent on the next as a source of food
   15. Trophic Level - each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.
   16. Biotic Factor - Living Organisms
   17. Abiotic Factor - non-Living organisms 
   18. Habitat - The environment in which animals and plants live in an ecosystem
   19. Predators -animals that prey/hunt others
   20. Prey - animals that are hunted
   21. Carrying Capacity - the average population for organisms in an area
   22. Symbiotic - involving interaction between two different organisms living in close physical association
   23. Mutualism - symbiosis that is beneficial to both organisms involved
   24. Commensalism - One organism benefits while the other is not benefited but is unharmed
   25. Parasitism - one organism is benefited while the other isn’t and is harmed
   26. Predation - the preying of one animal on others
   27. Competition - the relationship between organisms that strive for the same resources in the same place
   28. Photosynthesis - the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
