Vocabulary
What term describes the maximum number of individuals an environment can support?
Carrying capacity
If births are greater than deaths, will the population increase or decrease?
Increase
Which type of growth forms a J-shaped curve?
Exponential growth
Name ONE example of a limiting factor.
Food, water, space, disease, weather, etc.
Would a natural disaster most likely cause immigration or emigration?
Emigration
What term describes factors that limit population size, such as food, water, or disease?
Limiting factors
Write the formula used to calculate population change.
Answer: (Births + Immigration) − (Deaths + Emigration)
Which type of growth levels off as resources become limited?
Logistic growth
Would a drought most likely increase or decrease carrying capacity?
Decrease
Which population factor is most affected by access to healthcare?
Death rate
What type of population growth starts slowly, increases rapidly, then levels off?
Logistic growth
A population has 100 births, 40 deaths, 30 immigrants, and 20 emigrants. What is the population change?
+70
(100 + 30 − 40 − 20)
What causes a population to shift from exponential to logistic growth?
Limiting factors / reaching carrying capacity
How does disease affect population size?
Increases death rate / lowers population
Why do large cities often rely on immigration for growth?
Lower birth rates and high movement of people
What term describes individuals moving INTO a population?
Immigration
If a population starts at 5,000 and the population change is −250, what is the new population?
4,750
On a graph, what does the flat part of a logistic curve represent?
Population stabilizing at carrying capacity
How does habitat fragmentation affect carrying capacity?
Reduces livable space and resources
How could climate change affect future population growth in a city?
Changes resources, increases disasters, affects livability
What vocabulary term refers to the difference between births and deaths in a population?
Natural increase
A city has more immigration than emigration, but deaths exceed births. Name TWO factors affecting population change.
Immigration and deaths (migration and death rate)
Which growth type is more realistic for human populations in cities, and why?
Logistic growth because resources and space are limited
Explain how urbanization can act as BOTH a positive and negative factor for population growth.
Creates jobs/resources but limits space, increases pollution, strains resources
Predict how population growth could affect water availability in a fast-growing city.
Increased demand may reduce supply and lower carrying capacity
