Front 1

cosmic forces kept the delicate balance between organisms and their environment, studied by theologians

Back 1

balance of nature

Front 2

Limiting factors acting from outside the population

Back 2

extrinsic limiting factors

Front 3

Limiting factors acting from inside the population

Back 3

intrinsic limiting factors

Front 4

Extrinsic limiting factors: Competition, Predation,Symbiosis

Back 4

biotic limiting factors

Front 5

Extrinsic limiting factors: Sunlight, food, water, nutrients, resources

Back 5

abiotic limiting factors

Front 6

Limiting factors acting in proportion to how dense the population has become

Back 6

density-dependent limiting factor

Front 7

Limiting factors having the same effect regardless of how dense the population has become (forest fires, tidal waves)

Back 7

density-independent limiting factor

Front 8

Theory proposed by Charles Elton that equilibrium in nature resulted from a balance of interactive forces, especially competition and predation, stresses the importance of disturbance

Back 8

non-equilibrium theory

Front 9

forces that disrupt a natural ecosystem

Back 9

disturbance

Front 10

occurs when two or more organisms use the same resource in a way that affects the birth rate or death rate of the competitors

Back 10

competition

Front 11

Competition between members of same species

Back 11

intraspecific competition

Front 12

Competition between members of different species

Back 12

interspecific competition

Front 13

is the ecological role that a species plays in a biological community, the sum total of its needs and the parameters within which it can survive

Back 13

niche

Front 14

Determines intensity of competition between two species occupying different niches

Back 14

niche overlap

Front 15

Ability of either species to realize its full potential

Back 15

fundamental niche

Front 16

Narrower niche in which competition forces species into

Back 16

realized niche

Front 17

Occurs when one species is a better competitor than another, and forces it into local extinction

Back 17

competitive exclusion

Front 18

Flocks of hunting birds consisting of multiple species that coexist by occupying different niches

Back 18

mixed-species foraging flock

Front 19

Live in same geographic area, same habitat, use it at same time of day, but exploit the resource in a different way

Back 19

resource partitioning

Front 20

Modify a species physical shape through natural selection

Back 20

character displacement

Front 21

A form of competition which focuses on the strategy of exploiting resources by using them up

Back 21

scramble competition

Front 22

Type of competition in which species engage in a face to face contest over limited resources

Back 22

contest competition

Front 23

any area that any animal defends against other animals

Back 23

territory

Front 24

Bachelor males that do not mate in territory based society due to lack of territory to defend

Back 24

floaters

Front 25

Any organism that eats another organism

Back 25

predator

Front 26

Predatorial strategy based on kill it and eat it

Back 26

true predator

Front 27

Predatorial strategy based on insects lay their eggs in hosts (often paralyzed), young hatch, eat host alive

Back 27

parasitoid

Front 28

Strategy for hunting based on chase it and kill it

Back 28

active pursuit

Front 29

hide, wait for prey to come to you

Back 29

Ambush Predator
