Concepts Of Biology-Ch.27

Front 1

Mutualism

Back 1

Symbiotic interaction that benefits both partners

Front 2

Competition

Back 2

Competition between members of different species.

Front 3

Predation

Back 3

Interaction in which one organism (the predator) eats another (prey), typically killing it.

Front 4

Paratism

Back 4

Interaction in which one organism (the parasite) lives on or in another (the host) and feeds on its tissues.

Front 5

Symbiosis

Back 5

Close association of two or more species during part or all of the life cycle
Commensalism, mutualism, competition, predation, and parasitism are all forms of symbiosis

Front 6

Competitive exclusion

Back 6

Idea that, when two species require exactly the same resources, competition will drive one or the other to extinction in a shared habitat.

Front 7

Resource partitioning

Back 7

A subdividing of resources in time or space that allows similar species to coexist in a habitat.

Front 8

Coevolution

Back 8

Joint evolution of two interacting species, brought about by changes in selection pressures operating between the two.

Front 9

Camouflage

Back 9

Coloration, patterning, or other aspects of form or behavior that make an individual blend with its surroundings.

Front 10

Warning

Back 10

Pattern or coloration that makes a toxic organism (or its mimics) easy to detect and avoid

Front 11

Mimicry

Back 11

Close resemblance of one species to another; confers a selective advantage upon one or both species by deceiving predators.

Front 12

Pioneer species

Back 12

Species that can colonize newly formed or newly vacated habitats.

Front 13

Plant succession

Back 13

Sequence of community development from pioneer species to climax stage in a previously barren habitat;Recovery of a community to its climax stage following a habitat disturbance, such as a forest fire.

Front 14

Keystone species

Back 14

A species that has a major role in shaping community structure.

Front 15

Exotic species

Back 15

A species that has left the community in which it evolved and become established elsewhere.

Front 16

Indicator species

Back 16

Any species that provides warning of changes in habitat and impending widespread loss of biodiversity.

Front 17

Endangered species

Back 17

An endemic (native) species that is highly vulnerable to extinction.

Front 18

Habitat loss

Back 18

Reduction of habitat for a species as a result of environmental destruction.

Front 19

Conservation biology

Back 19

Field devoted to surveying biological diversity, studying its origins, and attempting to maintain it.
