Q

Density Dependent population control
VS.
Density Independent population control

A

Dependent -Depends on amount of population have a GREATER effect as population RISES

  • Spread of Disease
  • Predation
  • competition for resources

Independent -Affect population size. Does not matter on Population

  • Floods
  • drought
  • Fires

Q

Calculate annual rate of population change

  • Globally: Birth 22, Death 9
  • Africa: Birth 25, Death 14
  • Latin America: Birth 24, Death 6
  • Oceania: Birth 18, Death 7
  • U.S: Birth 15, Death 9
  • Europe: Birth 10, Death 11
A
  • Globally: Birth 22, Death 9 = .013
  • Africa: Birth 25, Death 14 = .011
  • Latin America: Birth 24, Death 6 =.018
  • Oceania: Birth 18, Death 7 = .011
  • U.S: Birth 15, Death 9 =.006
  • Europe: Birth 10, Death 11 .001

Q 
Determine the rate of population change 
Starts: 1 million
Births: 1675
Deaths: 450
Immigrants: 325
Emigrants: 150
A

s
1675 + 325 -150 -450
——————————- x 1,000 =1.4%
1,000,000 total

Q

Why is replacement level fertility not equal to 2.0?

A

da fuk type of question is this??????????????

20
Q

Factors (Social, biological, political) that effect Birth Rate and Fertility Rate

A

Social- Prices of food, education, etc.
Biological- many babies in poor countries dies
Political- Some countries limit # of children

21
Q

The rapid growth of the worlds population over the last 100 years is primarily the result of what?

- Higher Standards of Living

22
Q

SKIP :)

A

SKIP :)

23
Q

Name the two most useful indicators of overall health of people in a region/ country.

A
  • Infant mortality rate

- Life expectancy

24
Q

Population Age Structures

A

The wird pyramid shaped things

25
Q

Slowing/Stopping population growth
VS.
Not that

A

less kids = slowing population growth. No Shit

26
Q

Thomas Malthus and his essay on population

A

Unchecked population growth would lead to MAJOR problems.

27
Q

what is biotic potential?

A

Biotic potential is the maximum reproductive capacity of a population under optimum environmental conditions.

28
Q

Density Dependent Limiting Factors
VS.
Density Independent Limiting Factors

A

Dependent -Depends on amount of population have a GREATER effect as population RISES

  • Spread of Disease
  • Predation
  • competition for resources

Independent -Affect population size. Does not matter on Population

  • Floods
  • drought
  • Fires
29
Q

What are the survivorship curves and the different types?

A

A sideways “S” curve. Pop rapidly rises before leveling out

30
Q

How does Women’s education level affect the family size?

A

Less educated women have more children to join the labor force

31
Q

Why do women have more children in developing countries

A
  • To Work for them
  • To support them
  • Children/ Babies dies easier in developing countries
32
Q

what does the 1990 US Census say about the future total fertility rate of the US

A

It is declining

33
Q

FRQ -TFR
TWO reasons why does TFR Decline?

Why does Kenya have a higher TFR (TWO)

Two human activities that impact biodiversity

A
  • more women working = less need of child labor
  • Better Healthcare = less infant deaths
  • Higher infant death rate (no good care)
  • more agricultural (need kids to farm n shit)
  • Deforestation for houses and farms
  • Pollution from CO2
34
Q

FRQ Diseases
SARS- Transmission and solution
Malaria- Transmission and solution
Factor contributing to spread

A

SARS- Spreads from ANIMALS to HUMANS
-Keep animals away from humans
Malaria- Through Mosquito
- use bug spray, avoid mosquito land

  • Higher population density, increased likelihood of transmissions
  • More Travel (D)
35
Q

FRQ MEAT
per-capita meat production

Why more efficient to produce grain?

Environmental impact of meat (TWO)

+ AND - TO VEGITARIANISM

A

52 Billion

  • ————- = 20 kg per capita (100% increase)
    2. 6 billion
  • Less land to grow
  • Less energy to store grain
  • oVERGRAZING
  • WATER POLLUTION FROM SHIT

+LESS CHANCE OF CANCER
- LESS PROTEIN

36
Q

Last FRQ
