4.1 Population Dynamics

Front

What does logistic growth represent in population dynamics?

Back

Logistic growth describes a population that increases rapidly at first but then slows as it approaches the carrying capacity of the environment.

Front

What type of density dispersion do deer exhibit when they live and travel in herds?

Back

Deer exhibit clumped density dispersion.

Front

What must occur for a population's growth curve to continue increasing?

Back

The resources in the environment must be unlimited.

Front

What is the term for the movement of individuals into a population?

Back

Immigration.

Front

Define carrying capacity in the context of population dynamics.

Back

Carrying capacity is the maximum population size of a species that the environment can sustain indefinitely.

Front

What is the difference between immigration and emigration in population dynamics?

Back

Immigration refers to individuals moving into a population, while emigration refers to individuals moving out of a population.

Front

What is exponential growth in population dynamics?

Back

Exponential growth occurs when a population increases by a constant proportion over time, leading to a rapid increase.

Front

What factors can limit population growth?

Back

Factors that can limit population growth include resource availability, predation, disease, and environmental conditions.

Front

What is the significance of the carrying capacity in an ecosystem?

Back

The carrying capacity indicates the maximum number of individuals that an environment can support without degrading.

Front

How does competition affect population dynamics?

Back

Competition for limited resources can slow population growth and lead to changes in population size and structure.
