Population Dispersion

Front

What is carrying capacity in an ecological context?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can sustainably support without degrading the habitat.

Front

How can carrying capacity be determined from a population graph?

Back

Carrying capacity can be identified as the plateau or maximum level that the population reaches on the graph, indicating the limit of resources available.

Front

What is the formula for estimating a population using the capture-recapture method?

Back

The formula is: (Number of marked individuals in the second sample / Total number of individuals in the second sample) = (Number of marked individuals in the first sample / Total population size).

Front

What does random dispersion in a population mean?

Back

Random dispersion refers to a pattern where individuals are spread out in an unpredictable manner, often due to the availability of resources.

Front

What are the three main types of population dispersion patterns?

Back

The three main types are clumped dispersion, uniform dispersion, and random dispersion.

Front

What factors can affect the carrying capacity of an environment?

Back

Factors include availability of food, water, shelter, space, and the presence of predators or diseases.

Front

How does population density relate to carrying capacity?

Back

Population density is the number of individuals per unit area, and it can influence whether a population is below, at, or above carrying capacity.

Front

What is the significance of population dispersion in ecology?

Back

Population dispersion affects mating patterns, resource availability, and competition among individuals.

Front

What is clumped dispersion and why does it occur?

Back

Clumped dispersion is when individuals are grouped together in patches, often due to uneven resource distribution or social behavior.

Front

What is uniform dispersion and what causes it?

Back

Uniform dispersion is when individuals are evenly spaced, often due to territorial behavior or competition for resources.
