Question & Answer: Populations – ANSWER KEY
Question
Answer
Individuals of a species living in the same place at the same time?
Population
Changes in a population over time?
Dynamics
The amount of individuals in a population per unit habitat area?
Density
Spatial pattern of distribution where the individuals are grouped or
clustered together?
Spatial pattern of distribution where the individuals are evenly spaced
throughout the area?
Spatial pattern of distribution where the individuals are randomly
throughout the area because of resource locations?
This shape of age structure diagram shows positive population growth?
Clumped
This shape of age structure diagram shows zero population growth?
Straight edges
This shape of age structure diagram shows negative population growth?
Inverted Pyramid/urn
Exponential growth results in a graph of what shape?
J-shape
The change in population over time (growth rate) is represented by this
letter?
This equation/rule helps a scientist determine the amount of time required
for a population to double in size?
These factors affect populations randomly; examples include fire, drought,
flood?
These factors affect populations with high density (large numbers);
examples include disease and interactions like competition/predation, etc.
Logistic growth results in a graph of what shape?
r
The number of organisms an environment can support?
Carrying capacity
Carrying capacity is represented by this letter?
K
This type of species gives birth to many offspring because they provide
little care/protection and this results in most offspring dying before
reaching reproductive age?
This type of species gives birth to fewer offspring because they provide a
lot of care/protection so much of the offspring survive to reproductive
age?
This type of graph shows the relationship between age and mortality?
r-selected
This type of survivorship curve is representative of r-selected species?
Type III
This type of survivorship curve is representative of K-selected species?
Type I

researchers to perform several “captures” of the population in study?
