100
organisms such as humans that have low infant death rates and long life spans
What is type 1 survivorship?
100
growth that is rapid followed by a steady period
What is logistic growth?
100

A sharp decrease in population size when resource depletion leads to several individuals dying

What is die-off?

100
number of organisms per unit area
What is population density?
100
all members of a species living in the same area at the same time
What are populations?
200
Organisms that reproduce young and have many offspring
What are r selected organisms?
200
the rate at which population would grow with unlimited resources (not realistic)
What is intrinsic rate of increase?
200
graph for exponential growth
What is a J shaped curve?
200

how would you calculate NATURAL increase in population?

What is total births minus deaths?

200

When a population briefly exceeds carrying capacity

What is overshoot?

300

The total value of goods and services produced in a country

What is GDP?

300
organisms that reproduce late and have few organisms
What are k selected organisms?
300

Factors that influence populations regardless of size

What are density-independent factors?
300

Key health indicator of standard of living

What is life expectancy?

300

Factors that influence population growth, based on size

What are density-dependent factors?

400
capacity for popualtion growth under ideal conditions
What is biotic potential?
400

The process of economic and social transition from farming to manufacturing

What is industrialization?

400
the average number a woman must bear to replace current population
What is the replacement level fertility rate?
400

the doubling time if the population has an annual growth rate of 20%

What are 3.5 years?

400

The type of growth, that is rapid initially, then has limiting factors like competition that slow growth.

What is logistic growth?

500

Stage of social transition with very high per capita GDP and high life expectancy

What is Stage 4?

500

Survivorship curve type that shows, high mortality early in life, and few make it to midlife, and even fewer to adulthood

What is a type III curve?

500

Stage of demographic transition with shorter life expeactancy, high tfr, High infant mortality, but modernizations bring access to clean water and healthcare

What is Stage 2?

500
this is calculated by (birth + immigration) - (death + emigration)
What is the popualtion growth rate?
500

Three ways organisms can be distributed in a population

What is random, uniform, and clumped?
