k

Question 28

carrying capacity

Answer 28

limit to how many organisms an ecosystem can support

Question 29

we don't know because humans keep innovating

Question 30

what caused human growth rate to decline

rule of 70

Answer 32

you can approximate the doubling time of a population by taking the number 70 and dividing by the number of the rate (not the percent --> js take the number)

times

Answer 35

show birth/death rate and total population (there are multiple lines)

Question 36

Answer 36

4

Question 37

what are the phases of the demographic transition model

preindustrial phase

preindustrial phase has a ____ (high/low/declining/inclining) birth rate and a ____ (high/low/declining/inclining) death rate

Answer 39

high; high

Question 40

cause of death and birth rates in preindustrial phase

Answer 40

high death -- high child mortality bc no health care --> also a lot of people high birth -- not alot of women in the work force + kids keep dying so ppl keep having kids

Question 41

2nd phase of demographic transition model

Answer 41

transitional phase

transitional phase has a ____ (high/low/declining/inclining) birth rate and a ____ (high/low/declining/inclining) death rate

Answer 42

high;declining

Question 43

cause of birth and death rates in transitional phase

Answer 43

high birth: ppl don't realize kids aren't dying declining death: industrialization

Question 44

which phase adds significantly to the population(spike)

Answer 44

transitional

Question 45

do all populations stay for the same AMT of time in all demographic transition models

Answer 45

no diff for all

industrial phase has a ____ (high/low/declining/inclining) birth rate and a ____ (high/low/declining/inclining) death rate

Answer 47

declining; low

Question 48

cause of birth and death rates in industrial phase

Answer 48

birth: ppl realize kids aren't dying + women in the workforce death: was declining and is now low

Question 49

4th phase of demographic transition model

Answer 49

post industrial

Question 50

Answer 50

low; low

Question 51

cause of birth and death rates in post industrial phase

Answer 51

they were both declining so now they're low

Question 52

problems with post industrial phase

Answer 52

older ppl -- how support? resources?

Question 53

which phase causes a shrink in population size explain

Answer 53

post industrial bc the birth rate can go below the death rate bc ppl are working

Question 54

usual cause for decreasing birth rate with stabilizing population

Answer 54

Increased access to reproductive education and family planning generally decreases fertility rates because it allows families to plan the timing of pregnancies and to obtain prenatal care.

Question 55

cause for declining birth rate in post industrial phase

Answer 55

Countries in Stage 4 tend to have well developed economies and accessible education and healthcare, so as employment opportunities for females increase, families are more likely to shorten child bearing years and limit family size.
