All Flashcards
Effect of unlimited resources on population growth?
Leads to exponential growth and a J-shaped curve.
Effect of exceeding carrying capacity?
Can lead to a population crash due to resource depletion.
Cause of logistic growth slowing?
Environmental resistance and approaching carrying capacity.
Cause of population growth?
Influenced by competition, biome, and self-sufficiency.
Effect of limited food supply on deer population?
Slowing of the population growth rate.
Effect of increased competition on deer population?
Slowing of the population growth rate.
Effect of increased predation on deer population?
Slowing of the population growth rate.
Effect of resource depletion due to deer overpopulation?
Population crash.
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.
What is 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.
What is logistic growth?
Population grows exponentially then slows as it approaches carrying capacity, forming an S-shaped curve.
Define carrying capacity (K).
The maximum population size an environment can sustain.
What is environmental resistance?
Factors that slow population growth, such as limited resources.
Define overshoot.
When a population exceeds its carrying capacity.
What is a population crash?
A sudden decline in population size, often after an overshoot.
Define biome.
The environment a species lives in.
What is self-sufficiency?
How well a species can provide for its own needs.
