Population can be defined as_______.
A group of organisms of the same species living together in the same geographical location at the same time
Describe the Lag phase
Organisms have just begun to settle. Most are young, so reproduction is slow. They are getting used to the environment.
Describe the Log/Exponential phase
Organisms have now been well adapted. Reproduction rate is high (biological potential realized). Abundance of resources available.
Describe the Stationary phase
Environmental resistance begins to operate as carrying capacity is reached. food and resources as they become less available. Population size stabilizes.
Biotic potential refers to the ________ ________ ____ a species can attain.
maximum reproductive rate
Carrying capacity is the ____.
maximum population size of a species that a habitat can support for an extended period without disturbance.
What is environmental resistance?
the force of the limiting factors acting together, preventing the maximum reproductive potential from being achieved.
Limiting factors are___
abiotic or biotic factors that limits the number of individuals living in an area or population.
What is the difference between density-dependent and density-independent
density dependent is biotic while density independent is abiotic.
