population growth Flashcards
1
Q
lag phase
A
slow growth, time to reach sexual maturity
2
Q
log phase
A
increase in numbers, no limiting factors, environmental resistance reduces growth
3
Q
stationary phase
A
birth=death
reached carrying capacity, fluctuations
4
Q
death
A
death exceeds birth
5
Q
biotic factors
A
living components
e.g food supply, predators
6
Q
abiotic factors
A
non-living components
e.g temperature, humidity
7
Q
density dependant
A
effect of factors increases as population density increases
e.g food supply
8
Q
density independent
A
same effect regardless of population size
e.g sudden temp change
