Enviromental Science

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

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

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 isnt 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
