Population Growth
A group of the same species living in the same place at the same time.
What is a population?
These can slow down the birthrate and increase the death rate.
What are limiting factors?
This is the type of growth represented by a j-shaped curve.
What is exponential growth?
An upside down pyramid indicates that a population is doing this.
What is decreasing?
This is the dispersion of individuals when they are grouped together in many places throughout their environment.
What is clumped?
The maximum number of individuals an environment can support for a long period of time
What is Carrying Capacity?
Predation, competition, and parasitism & disease are all considered these.
What are density-dependent limiting factors?
This is growth represented by an S-shaped curve and is controlled by limiting factors.
What is logistic growth?
A pyramid shape indicates that a population is doing this.
What is increasing?
This dispersion is characterized by individuals living a specific distance from each other in a population.
What is even?
Population growth is affected by these four factors.
What is # of births, # of deaths, immigration and emigration?
Natural disasters and unusual weather are considered these.
What are density-independent limiting factors?
This is the type of growth that occurs when the population slows or stops after a period of rapid growth.
What is logistic growth?
This is the type of country that has rapid population growth due to need for many young individuals and lack of contraception.
What is a developing country?
This dispersion is characterized by individuals spread out in an area with no uniformity or clear pattern.
What is random?
Geographic distribution, population density, and age structure are three characteristics of a population. This is the fourth.
What is growth rate?
Wolves fighting for a small supply of rabbits for food is a _____________________ limiting factor.
What is density-dependent?
This is the type of population growth that occurs when there are unlimited resources and the population grows very quickly at a constant rate.
What is exponential growth?
A age structure shape that has the majority of individuals being middle-aged and very few being very young and very old indicates a population is doing this.
What is remaining stable?
Population density is calculated by dividing these two measurements.
What are the number of individuals in a population by the area they live in?
number of deaths + number of emigrants > number of births + number of immigrants will cause this to happen to the population.
What is Population decrease?
A drought, along with a disease has affected a deer population. This is an example of...
a. Density-independent
b. Density-Dependent
c. Both
What is C?
Growth of a population is directly determined by this.
What is the availability of resources?
These types of countries have low birth rates, low death rates, financial stability, and easy access to health care.
What are developed countries?
This is the unit of measurement used to measure the area in which a population lives.
What is meters squared or kilometers squared?
