EOC population dynamics Review 1

Front

What pattern of growth will a population with limited resources show?

Back

Logistic growth is characterized by an initial exponential increase followed by a leveling off as resources become limited.

Front

What type of growth model is characterized by a rapid increase in population size without any limiting factors?

Back

Exponential growth model describes a population that grows rapidly when resources are abundant.

Front

What is the term for a sequence of biotic changes that regenerate or create an ecological community?

Back

Succession is the process through which ecosystems change and develop over time.

Front

Which of the following is NOT a key feature of populations?

Back

Disease is not considered a key feature of populations; key features include size, density, and dispersion.

Front

Isle Royale National Park is located in which body of water?

Back

Lake Superior.

Front

What is density-dependent factor in population dynamics?

Back

Density-dependent factors are conditions whose effects on the size or growth of a population vary with the population density.

Front

What is the difference between Type I and Type III survivorship curves?

Back

Type I curves show high survival rates in early and middle life, while Type III curves show low survival rates for the young.

Front

What is carrying capacity in the context of population dynamics?

Back

Carrying capacity is the maximum population size that an environment can sustain indefinitely without degrading.

Front

What is the significance of the logistic growth model in ecology?

Back

The logistic growth model helps predict how populations grow in environments with limited resources.

Front

What are biotic factors in an ecosystem?

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms.
