Carrying Capacity and Limiting Factors
This determines the carrying capacity of an ecosystem
What is limiting factors?
This is what populations do until they reach their carrying capacity
What is increase?
These are the limiting factors that influence population dynamics.
What are food availability, human interference, and disease?
This growth curve is S-shaped, showing realistic conditions with limiting factors present.
What is a logistic growth curve?
This is the species that lived on St Matthew Island and had a massive spike in population before crashing in less than two decades.
What are reindeer?
This is what can cause a carrying capacity to change.
This is what happens to a population if limiting factors stay the same.
What is stays around the carrying capacity?
This is what we can learn about by looking at population dynamics.
What are predator-prey relationships, biodiversity, and population density?
This growth curve is J-shaped, showing idealistic conditions with essentially unlimited resources.
What is an exponential growth curve?
This is what caused the extinction of the Dodo Bird
What is overhunting?
Temperature, weather, and water are examples of this kind of limiting factor
What is abiotic
These are the things that can cause limiting factors to change (give two).
What are natural disasters, habitat destruction, pollution, overhunting?
This is the definition of population density.
What is the amount of organisms in a specific area?
This is what exponential growth curves never hit, showing the lack of limiting factors.
What is carrying capacity?
This organism is an example of exponential growth, doubling every hour.
What is bacteria?
This is what makes a biotic factor different from an abiotic factor
What is biotic factors are alive?
These are the things that can happen after a population overshoot (give two).
What are resource depletion, habitat destruction, increased competition for resources, and population crash/die-off?
This the definition of an invasive species.
What is a non-native species that harms their environment and other organisms?
This is the length of time a species can create viable offspring
What is how long they reproduce?
This species is an example of an invasive species, wiping out native clam species and disrupting underwater infrastructure.
What are zebra mussels?
This is the definition of carrying capacity.
What is the maximum population an ecosystem can support?
What can staying below carrying capacity lead to?
What is stability and healthy growth?
This is a species that influences their ecosystem a lot compared to the amount of the species that lives there.
What is a keystone species?
What is death rate of a population?
This species is a keystone species, being environmental engineers through building dams.
What are beavers?
