Back 2

NCHOPS
Nitrogen, carbon, hydrogen, oxygen, phosphorus and sulfur

Front 3

s curve

Back 3

Natural things come in the way and cause population to level and hit an equilibrium.

Front 4

j curve

Back 4

the point when there are no natural predators ussually resulting in over grazing then dying of starvation or diesies

Front 5

Primary succesion

Back 5

An area that is not previously occupied. the are initial invasion, progression from biotic community. moss on rock

Front 6

secondary succesion

Back 6

a re invasion of a biotic community that was destroyed by things like fire or humans. Steps are crab grass, tall grass, pines, pine forest ext...

adaptions wich support survival

Back 7

1.) coping with climate and abiotic factors
2.)Adapting to obtain water and nutrients
3.)Adaption against predators
4.)Adaption of reproductive advantage
5.)Adaption for migration

Front 8

natural selection ands relate it to a species

Back 8

survival og the fittest- darwin

give the age structure of populations.

Front 10

consumer's

Back 10

organisms that derive their energy from feeding on other organisms or their products

Front 11

differential

Back 11

within a population the more successful reproduction of certain individuals compared with that of others

Front 12

gene pool

Back 12

the sum total of all the genes that exist among all the individuals of species

Front 13

monoculture

Back 13

the practice of growing the same crop year after yearon the same land

Front 14

polyculture

Back 14

the growing of two or more species together

Front 15

selective

Back 15

the breeding of cetain individuals because they bear certain traits and the exclusion from breeding of others

Front 16

speciation

Back 16

the evolutionary process whereby populations of a single species separate and through being exposed to different forves of natural selection,gradually develop into distinct species

Front 17

trait

Back 17

any physical or behavioral characteristic or talent that an individual is born with

Front 18

omnivore's

Back 18

an animal that feeds on both plant material and other animals

Front 19

autotrophs

Back 19

any organism that can synthesize all its organic substances from inorganic nutrients using light or certain inorganic chemicals as a source of energy. green plants are the principal autotrophs

Front 20

demographics

Back 20

the transition of a population from a condition of a high birthrate and a high death rate to a condition of a low birthrate and a low death rate.may result from economicor social development

Front 21

developed/industrialized countries

Back 21

US,Canada,western european nations, japan, australia,and new zealand, in which the gross domestic product exceeds $9,360 per captia

Front 22

biodiversity

Back 22

the diversity of living things found in the natural world. the concept usually refers to the different species but also includes ecosystems and the genetic diversity within a given species

Front 23

biota

Back 23

the sum total of all living organisms. applied to the setting of natural ecosystems

Front 24

abiotic

Back 24

pertaining to factors or things that are separate and independent from living things;non living

Front 25

biotic potenial

Back 25

reproductive capacity. the potential of a species for increasing its population and/or destribution.every species is such that,given optimum conditions, its poplulation will increase

Front 26

decomposers

Back 26

organisms whose feeding action results in decay or rotting or organic material. the primary decomposers are fungi and bacteria

Front 27

extinction

Back 27

the death of all individuals of a particular species. when this occursall the genes of that particular lline are lost forever.

Front 28

mutation

Back 28

a random change in one or more genes of an organism. mutations may occur spontaneously in nature, but their number and degree are vastly increased by exposure to radication or certain chemicals. mutations generally result ina physical deformity or metabolic malfunction

Front 29

producers

Back 29

in an ecosystem those organisms which use light engery to construct their organic constituents from norganic compounds

Front 30

tectonic

Back 30

huge slabs of rock that make up Earth's crust

Front 31

carnivores

Back 31

an animal that feeds more or less exclusively on other animals

infant mortality

Back 32

the number of babies that die before one year,per

Front 33

total fertility rate

Back 33

the average number of children that would be born alive to each woman during her total reproductive years if her fertility was average at each age
