Population
______ is all members of a species living in the same place at the same time.
Population
_____ is the change in size or population of an organism or group of organisms over a specific period of time
Growth rate
A pattern where an population increases in size by a constant amount per unit of time, this is called?
Linear Growth
This is called an S curve.
Logistic Growth
_______ is the arrangement of a population’s individuals within a given amount of space.
Population Dispersion
______ is the number of individuals per unit area.
Population Density
_____ is the maximum number of offspring that a given organism can produce.
Reproductive Potential
This graph is called a “J” curve
Expontanial growth
______ shows the probability of survival for a given group or species.
Survivorship Curve
Where it levels off on an S curve is called _____.
carrying capacity
______ is a population distribution pattern where individuals are spaced out more or less evenly
Uniform Dispersion
When there is no increase or decrease in a quantity over a specific period, this is called?
Zero population growth rate
_____ is the number of organisms that an environment can support over a long period of time
Carrying capacity
______ shows a snapshot of the current population. Gender and age.
Population Pyramid
_______ means that the population of a given area is increasing over time.
Positive Population growth rate
_______ is a distribution pattern where individuals of a species are spaced at unpredictable distances from each other
Random Dispersion
When the population of a region is decreasing, indicating more deaths or people are leaving than births, this is called?
Negative population growth rate number
A situation where a population increases at a constant rate proportional to its current size, this is called?
Exponential Growth
_______ is a type of reproduction that reproduces quickly to ensure many offspring.
R Strategists
When the factors affect all populations, regardless of how large.
Density-independent
What is the population density equation?
# of organisms/space
What is the growth rate equation?
Births + Deaths = Growth Rate
Are ecological forces that affect population size in response to the population's density, or the number of individuals per unit area, called?
Density-dependent factors
______ is a reproduction that reproduces more slowly with fewer offspring.
K Strategists
There are 12 pandas in a 1sq meter crib. Calculate the density of the population.
12 panda per sq. meter
