U9 Population vocab 1st half

What is an example of a density-dependent factor affecting a population?

• Predation pressure increasing as prey population size grows.
• Rainfall patterns in a region.
• Amount of sunlight in an ecosystem.
• Temperature fluctuations in an environment.

Which of the following is an example of a density-independent factor affecting a population?

• Forest fires destroying a large area of habitat.
• Availability of nesting sites for birds.
• Predator-prey interactions in a community.
• Competition for food among individuals.

What is a density-independent factor in population ecology?

• A factor that influences population growth regardless of the population's density.
• A factor that is controlled by the population.
• A factor that only affects large populations.
• A factor that is related to population size.

What is a density-dependent factor in population ecology?

• A factor that influences population growth in relation to the population's density.
• A factor that only affects small populations.
• A factor that is constant regardless of population size.
• A factor that is not related to the environment.

What is population density?

• The number of individuals of a species per unit area or volume.
• The total number of individuals in a population.
• The number of species in an ecosystem.
• The amount of resources available in an environment.

Which of the following is an example of a density-independent factor that can affect population growth?

• Natural disasters
• Predator-prey interactions
• Availability of suitable habitat
• Competition for resources

What is the term used to describe the maximum number of individuals of a species that an environment can support?

• Carrying capacity
• Biological diversity
• Resource allocation
• Habitat restoration

What is the term used to describe a field of study about populations of specific species and how they interact with their environment?

• Population ecology
• Behavioral ecology
• Community ecology
• Conservation biology

Which of the following best explains why populations cannot grow exponentially indefinitely?

• Resources in any environment are eventually limited.
• All populations eventually evolve to stop growing.
• Predators always limit the population size.
• Weather conditions prevent unlimited growth.

In the context of population dynamics, what does it mean when a population reaches its carrying capacity?

• The population size stabilizes because birth rates equal death rates.
• The population will rapidly decline due to increased competition for resources.
• Population growth accelerates because resources are abundant.
• The population size temporarily exceeds the environment's ability to support it.
