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