Population Ecology (2024)

Front

What is the carrying capacity in population ecology?

Back

The maximum number of individuals of a species that an environment can support sustainably.

Front

What letter represents the carrying capacity in ecological graphs?

Back

D

Front

How is population density defined?

Back

The number of individuals of a species per unit area.

Front

What is the equation for calculating population density?

Back

Front

What is a mark and recapture study?

Back

A method used to estimate the size of wildlife populations by capturing, marking, and releasing individuals, then recapturing them later.

Front

If 100 fish are marked and released, and later 50 are recaptured with 10 marked, how do you estimate the total population?

Back

Use the formula: Total Population = (Number of marked fish initially * Total number of recaptured fish) / Number of marked fish recaptured. Estimated population = 500 fish.

Front

What does population distribution refer to?

Back

The way individuals are spaced within their habitat, which can be clumped, uniform, or random.

Front

What is the difference between population density and population distribution?

Back

Population density measures how many individuals are in a specific area, while population distribution describes how those individuals are spread out.

Front

What factors can affect carrying capacity?

Back

Food availability, habitat space, water supply, and environmental conditions.

Front

What is the significance of the carrying capacity in ecology?

Back

It helps in understanding the limits of population growth and the sustainability of ecosystems.
