What would be the growth rate (r) of an island population of 1000 that has 30 births per 100 population, 20 death per 100 population, 5 immigrants per 100 population, and 10 emigrants per 100 population?

+50

Based on the accompanying figure, which of the following age intervals has the highest death rate?

0-1

Refer to the accompanying figure. A population that produces a large number of offspring, but the offspring must survive independently, would be represented by the curve labeled:

A

Refer to the accompanying figure. At which point on the graph is the population increasing exponentially?

B

On the accompanying figure, identify the point that indicates the carrying capacity for this population.

D

____ are good habitats where local reproductive success is greater than local mortality.

Source habitats

Clumped dispersion is often influenced by:

a patchy distribution of resources

Check My Work Which of the following consists of organisms, all of which share a common gene pool?

a population

The percentages of a population at different ages are known as the:

age structure

Density-independent factors:

are typically abiotic

Which set of values would result in a population with a growth rate of zero?

b = 1000, d = 500, i = 500, e = 1000

____ is the least frequent of the dispersal patterns seen in nature.

random dispersion

The logistic equation:

takes into account the carrying capacity of the environment

The organisms associated with patches of floating ocean vegetation would be an example of:

clumped dispersion

The equation that would best describe the curve in the accompanying figure is:

dN / dt = rN.

Check My Work The moose population on Isle Royale is an example of:
