100
What is uniform distribution
Individuals living in an area have equal distance of space from one another
100
What is clumped distribution?
Individuals in an area live in a tight, distinct group. Each group has random amount of distance from other groups
100
Name 1 density-independent limiting factor
Flood, wild fire, earthquake
100
What is population density?
Number of individuals per unit area
100
Name 2 biotic limiting factors
Plants and animals
200
What is carrying capacity?
Maximum individuals that can be supported by the area and environment
200
A J-curve is also known as _______________
Exponential growth
200
Give one example of random distribution
Purple lupines grow randomly among wild flowers (page 131, Figure 5-2A.)
200

Which of the following populations has higher density? Choice a.) 25 pine trees in 2 squared kilometers Choice b.) 100 pine trees in 5 squared kilometers

Choice b.)

200
Name 1 density-dependent limiting factor
parasitism, diseases, competition, predation, overcrowding
300
What is an age structure?
Number of males and females of each age a population contains
300
An S-curve is also known as ___________
Logistic growth
300
What causes exponential growth to become logistic growth?
Carrying capacity
300
Name 3 abiotic limiting factors
Water, oxygen, space, nutrients, sunlight
300
What are some characteristics of population growth of small organisms?
Small organisms tend to grow rapidly but have short longevity
400
What is limiting factor?
Factor that controls population growth
400
Name 4 factors used by demographer to determine population growth
birth rate, death rate, immigration, and emigration
400
Name 5 types of factors that can limit population size
Competition, predation, parasitism and disease, unusual weather, and natural disaster
400
What factor(s) could potentially cause a population to have logistic growth?
Unlimited supplies for the survival of the population, such as unlimited food, water, oxygen, space, etc.
400
What are some characteristics of population growth of large organisms?
Large organisms tend to grow slowly but live a long life
500

What is geographic range?

The area inhabited by a population

500

The graph describes the changes that occur when a country undergoes the demographic transition, which involve changes to birth rate and death rate.

As explained by the graph, when does the population of the country increase most rapidly? Assume that both immigration and emigration are insignificant to the population size.

Stage 2

500
When does exponential growth occur?
When there are unlimited resources for the populations
500
Name 3 phases of population growth
Phase I: Exponential growth Phase II: Growth slos down Phase III: Growth stops
500
Describe the correlation between longevity of an organism and its size
Large organism tends to have long longevity Small organism tends to have short longevity
