Make an Example of Me
The number of organisms per unit area
What is population density?
The pattern of spacing of a population
What is distribution (or dispersion)?
The study of the size, density, distribution, and movement of human populations
What is demography?
The shape of a population pyramid for a rapidly expanding nation.
What is very broad-based?
This type of reproductive strategy is more likely used in biomes that undergo frequent changes in biotic or abiotic factors.
What are r-selected strategies?
Type of growth that slows or stops after a period of exponential growth, at the population’s carrying capacity.
What is logistical growth?
Slow population growth initially that increases rapidly as more organisms reach reproductive age.
What is exponential growth?
[(b + i) – (d + e)]
What is per capita population growth rate?
The term used to describe the number of individuals moving into an area.
What is immigration?
Habitat, availability of food, and predation are examples of these types of things that cause population growth to slow.
What are limiting factors?
The members of a single species that share the same geographic location at the same time.
What is a population?
The number of individuals moving away from a population.
What is emigration?
The population size that can be supported indefinitely by an ecosystem without destroying that ecosystem.
What is carrying capacity?
This type of reproductive strategy is most commonly seen in long-lived organisms who have and care for a few offspring at a time.
What are K-selected strategies?
Hurricanes, tornadoes, flooding, extreme heat or cold, and fire are examples.
What are density-independent factors?
A corn field, a Christmas tree farm, a male black bear.
What are examples of uniform dispersal patterns?
Parasites, disease, competition, and predation.
What are examples of density-dependent factors?
A school of fish, a herd of bison, a murder of crows.
What are examples of clumped distribution?
Elephants, humans, and whales.
What are examples of K-strategists?
Canada, New Zealand, Germany, Brazil.
What are examples of countries with stable population growth?
When one organism or population benefits while another suffers a loss.
What is antagonism (predation, grazing, parasitism)?
Occurs between different species.
What are interspecific interactions?
In this type of relationship, the graph of the interacting populations looks like this:
What is a predator-prey relationship?
Interaction between organisms where neither one benefits.
What is competition?
When species evolve to live harmoniously with others by using only a portion of the resources that both species need.
What is resource partitioning?
The final Jeopardy answer is:
The three types of ecological pyramids
What are pyramids of numbers, biomass, and energy?
