K is an abbreviation for this population level which doesn't start with "K".
What is carrying capacity?
100
Describe the birth and death rates during the first stage of Demographic Transition.
What are high birth and rates?
100
This rate is affected primarily by disease, medical care, and sanitation and unaffected by access to family planning.
What is the Death Rate?
100
X-axis = Time; Y-axis = log [Population]
The type of growth shown in this graph.
What is exponential growth?
100
Clownfish, whales or zooplankton.
These have the highest amount of parental care.
What are whales?
200
Food and living space are these types of factors that affect K.
What are limiting factors?
200
Describe the birth and death rates during the fourth (last) stage of Demographic Transition.
What are low birth and death rates?
200
This type of species typically have high mortality, high reproductive rates, and low amounts of energy invested per offspring.
What are r-selected species?
200
X-axis = Time; Y-axis = log [Population]
The type of growth shown in this graph.
What is Logistic Growth?

Afghanistan, India, Taiwan
This country has the lowest birth rate.
What is Taiwan?
300
This type of species typically have slow reproduction, long lives, and invest a lot of energy in caring for each offspring.
What are K-selected species?
300
In Stage 2 of Demographic Transition, better medical care and sanitation results in a low death rate. However, a high birth rate remains because of this.
What are cultural norms of having large families?
300
The total fertility rate is defined as this.
What is the average number of children born to a woman over her lifetime?
300
X-axis = Time; Y-axis = log [Population]
If not for Environmental Resistance, this pushes populations upwards to exponential growth.
What is Biotic Potential?
300
Argentina, Norway, Sudan
This country has the lowest death rate.
What is Norway?
400
This effect happens due to an increase of the population above K.
What is overshoot?
400
In Stage 3 of Demographic Transition, the birth rate begins to decline primarily because of these three reasons.
What are access to contraception (or family planning), increased access to education for women, increase of women in the work force?
400
Replacement Level Fertility is defined as how many children per woman?
What is 2.1 children per woman?
400
X-axis = Relative Age; Y-axis = log [Proportion Surviving]
The type of graph this is.
What is a Survivorship Curve?
400
Democratic Republic of the Congo, Japan, Kenya
This country has the highest Population Growth Rate.
What is the Democratic Republic of the Congo?
500
This effect happens after the population exceeds K and there aren't enough resources.
What is die back or die off?
500
Demographers use this fifth stage of Demographic Transition although it's not used for APES. In this stage, because of a very low birth rates, there is this type of population growth.
What is negative population growth?
500
The population growth rate is a percentage equal to this (state a math formula).
What is (Crude Birth Rate minus Crude Death Rate) divided by 10?
500
X-axis = Stage; Y-axis 1 = Births or Deaths per year; Y-axis 2 = Population
The type of graph this is.
What is a Demographic Transition Model?
500
Pandas, sea turtles, termites.
These have the highest fecundity.
What are termites?
