Increased bird migration
A decrease in mosquito predators
An explosion in the mosquito population
A new strain of the virus
What is a population?
(in the context of population ecology)
Any group of organisms
All the organisms in an ecosystem
A group of individuals of different species
A group of individuals of one species who interact regularly
Which factor is NOT a limiting factor for a population's growth?
Geographic location
Food availability
Temperature
Population size
What is the term for the maximum number of individuals an environment can support?
Population dispersion
Limiting factor
Carrying capacity
Population density
What are density-dependent limitations?
Factors that promote population growth
Factors that limit growth based on population size
Factors that only affect small populations
Factors that limit growth regardless of population size
How do population ecologists categorize limiting factors?
By whether they depend on population density
By whether they are biotic or abiotic
By their geographical impact
By their impact on population size
What does exponential growth in a population mean?
The population decreases over time
The population increases by a fixed number each generation
The population grows in proportion to its current size
The population remains constant over time
Match the following levels of classification to their definitions:
1 individual
Organism
All the same species
Population
All the different living things
Community
All the biotic and abiotic things
Ecosystem
The number of trout in a stream
Population size
The size of a population of bears in a certain area
Population density
How people or organisms are spread out in an area
Population dispersion
Carrying capacity is the (a) number of organisms that can survive in an area based on the available (b) , such as food and water.
Match the following terms and definitions
Organism
Something that is alive
Population
All the individuals of one kind (one species) in a specified area at one time
Ecosystem
A system of interacting organisms and nonliving factors in a specified area
Habitat

Biotic
