Front 1

edge effects

Back 1

differences in the physical structure at boundaries and in transition zones between two ecosystems

Front 2

native species

Back 2

species that normally live and thrive in a particular ecosystem

Front 3

nonnative species

Back 3

species that migrate into an ecosystem or are introduced into an ecosystem by humans

Front 4

indicator species

Back 4

species that serve as early warnings of damage to a community

Front 5

keystone species

Back 5

species that play roles affecting many other organisms in an ecosystem

Front 6

territoriality

Back 6

a way of species competition in which organisms patrol or mark an area around their home and defend it against members of their own species

Front 7

interspecific competition

Back 7

competition between members of tow or more different species for a limited resource

Front 8

interference competition

Back 8

competition in which one species may limit another's access to some resource

Front 9

exploitation competition

Back 9

competition in which species have roughly equal access to a resource but differ in how fast or efficiently they can exploit it

Front 10

resource partitioning

Back 10

the dividing up of scarce resources so that species with similar needs use them at different times, in different ways, or in different places
