  • Front
  • Back
A place where an organism lives and that provides for its needs.
HABITAT
A model used to show the feeding relationship in which many food chains overlap in an ecosystem.
FOOD WEB
All of the populations of different species that live and interact in an area
COMMUNITY
Represents how energy in food flows from one organism to the next.
FOOD CHAIN
A group of individuals of the same species that live together in the same area at the same time. (ex. all seaside sparrows living together in a salt marsh)
POPULATION
The branch of biology concerned with the relations between organisms and their environment.
ECOLOGY
Earth's entire living environment, including the land, sea, and atmosphere where life can be found.
BIOSPHERE
The organism that eats the prey. (bird eats worm-the worm is the prey and the bird is the predator)
PREDATOR
This is a type of relationship between consumers (animals) that eat other consumers (animals).
PREDATOR-PREY RELATIONSHIPS
Harmful substances that are released and make our planet dirty, noisy, or unhealthy.
POLLUTION
Two or more species or indivviduals trying to use the same limited resources.
COMPETITION
A consumer that eats plants.
HERBIVORE
The relation between two different species of organisms that are interdepe dent; each gains benefits from the other.
MUTUALISM
The disappearance of forests due to land development, cultivation, or lumbering.
DEFORESTATION
These are animals that feed on the bodies of dead animals. (example-turkey vulture from the prairie ecosystem or a smail or clam from an aquatic ecosystem)
SCAVANGER
The relation between two different kinds of organisms when one receives benefits from the other without damaging it.
COMMENSALISM
The amount of usable energy in an ecosystem is less for each higher animal in the food chain. Movement of energy through an ecosystem.
energy pyramid
Is a close, long-term association between two or more species. The individuals in this type of relationship can benefit from, be unaffected by, or be harmed by the relationship.
symbiosis
Consumer that eats both plants and animals.
omnivore
A system formed by the interaction of a community of organisms with their physical environment. (abiotic environment-temperature, soil, percipitation.)
ecosystem
All living and nonliving surroundings that affect an organism.
environment
Describes living factors in the environment. All living organisms that live together and interact with one another.
biotic
The nonliving factors in an ecosystem.
abiotic
The dissappearance of all members of a species from Earth.
extinction
The organism that is eaten by another living organism.
prey
A consumer who eats only other animals.
carnivore
A relationship between two organisms in which one rganism lives on or in the other, feeds upon it, and usually harms it.
PARASITISM
The largest population that a given environment can support over a long period of time.
CARRYING CAPACITY
The disappearance of forests due to land development, cultivation, or lumbering.
DEFORESTATION
These are animals that feed on the bodies of dead animals. (example-turkey vulture from the prairie ecosystem or a smail or clam from an aquatic ecosystem)
SCAVANGER
The relation between two different kinds of organisms when one receives benefits from the other without damaging it.
COMMENSALISM
The amount of usable energy in an ecosystem is less for each higher animal in the food chain. Movement of energy through an ecosystem.

Is a close, long-term association between two or more species. The individuals in this type of relationship can benefit from, be unaffected by, or be harmed by the relationship.

ecosystem
All living and nonliving surroundings that affect an organism.
environment
Describes living factors in the environment. All living organisms that live together and interact with one another.
biotic
The nonliving factors in an ecosystem.
abiotic
The dissappearance of all members of a species from Earth.
extinction
The organism that is eaten by another living organism.
prey
An organism's way of life within an ecosystem; includes its habitat, its food, its predators, & the organisms with which it competes.(Its ROLE)
