All Flashcards
What is the significance of competition in population growth?
Competition affects population growth rate by limiting resources.
What is the significance of carrying capacity in population dynamics?
Carrying capacity represents the maximum sustainable population size in a given environment.
What is the relationship between exponential and logistic growth?
Logistic growth often starts with exponential growth before environmental factors limit it.
Why is understanding logistic growth crucial?
It reflects real-world population dynamics, a frequent AP exam topic.
What happens after a population overshoots its carrying capacity?
It can lead to a population crash due to resource depletion.
How does environmental resistance impact population growth?
It slows down population growth as it approaches carrying capacity.
What conditions are required for exponential growth?
Unlimited resources and ideal environmental conditions.
What does a population graph's axes tell you?
They reveal whether you're dealing with exponential or logistic growth.
What is the impact of self-sufficiency on population growth?
How well a species can provide for its own needs.
How does the biome affect population growth?
The environment a species lives in, with all its unique challenges and resources.
What are the environmental consequences of exceeding carrying capacity?
Resource depletion, increased mortality, and potential population crash.
What is the effect of increased competition on population growth?
Slower population growth due to limited resources.
What causes a population to shift from exponential to logistic growth?
Increasing environmental resistance due to resource limitations.
What is the effect of unlimited resources on population growth?
Rapid, unchecked exponential growth.
What causes a population overshoot?
Delayed response to environmental limits or a sudden influx of resources.
What is the effect of limited water supply on population growth?
Slower population growth and increased competition.
What is the effect of limited food supply on population growth?
Slower population growth and increased competition.
What is the effect of limited space on population growth?
Slower population growth and increased competition.
What is the effect of increased predation on population growth?
Slower population growth.
What is the effect of increased disease on population growth?
Slower population growth.
Define population growth rate.
How populations change over time, influenced by their environment.
Define exponential growth.
Population increase at its maximum rate, leading to a J-shaped curve.
Define intrinsic rate of increase (r).
The maximum potential growth rate of a population.
Define logistic growth.
Population grows exponentially at first, then slows as it approaches carrying capacity, creating an S-shaped curve.
Define carrying capacity (K).
The maximum population size an environment can sustain.
Define environmental resistance.
Factors that slow population growth, like limited food, water, and space.
Define overshoot.
When a population exceeds its carrying capacity.
What is a J-curve?
The shape of the graph showing rapid, accelerating (exponential) growth.
What is an S-curve?
The shape of the graph, showing initial exponential growth followed by a leveling off (logistic growth).
Define biome.
The environment a species lives in, with all its unique challenges and resources.
