All Flashcards
Cause: Population exceeds carrying capacity. Effect?
Resource depletion, increased competition, potential die-off.
Cause: Limited resources. Effect?
Lower carrying capacity, slower population growth, increased competition.
Cause: Introduction of a new predator. Effect?
Potential population crash of prey species, altered carrying capacity.
Cause: Unlimited resources. Effect?
Exponential population growth (J-curve).
Cause: Increased birth rates. Effect?
Population growth, potential overshoot if resources are limited.
Cause: Increased death rates. Effect?
Population decline, potential stabilization at a lower level.
Cause: Famine in a population. Effect?
Die-off due to lack of food and resources.
Define 'population'.
A group of the same species living in a specific area.
Define 'Carrying Capacity (K)'.
The maximum number of individuals an ecosystem can support with available resources.
Define 'Population Overshoot'.
When a population exceeds its carrying capacity.
Define 'Population Crash (Die-off)'.
A rapid decrease in population size due to lack of resources after an overshoot.
Define 'Exponential Growth'.
Population growth with unlimited resources, resulting in a steep increase (J-curve).
Define 'Logistic Growth'.
Population growth that levels off as it approaches carrying capacity (S-curve).
What is the effect of exceeding carrying capacity?
Resource depletion, environmental damage, increased competition, and potentially a population crash.
What causes a population overshoot?
A period of rapid growth due to abundant resources, leading to a population size that exceeds the environment's carrying capacity.
What are the consequences of a population die-off?
A significant reduction in population size and potential long-term impacts on the ecosystem.
What is the effect of limited resources on population size?
Limited resources restrict population growth and lower the carrying capacity.
