Exam 53: Introduction to Ecology: Population Ecology

The logistic equation:

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

In Type-I survivorship, the young have a high probability of surviving. ____________________

The Earth's carrying capacity is:

When the size of a population greatly exceeds K, it would be expected the population will:

Generally, r-selected organisms exhibit:

Differentiate between density-dependent and density-independent factors affecting population growth.Provide two examples for each, along with a brief explanation.

A density-dependent factor is an example of a negative feedback system. ____________________

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

Communities are composed of:

Which of the following examples is incorrectly paired?

MATCHING Match the term in a growth rate equation with its definition. a.b e.K b.d f.N c.e g.r d.i -natality

MATCHING Match the term in a growth rate equation with its definition. a.b e.K b.d f.N c.e g.r d.i -number of individuals in a population

The moose population on Isle Royale is an example of:

Organisms such as oysters or fish that produce millions of eggs per year may be characterized as:

Using the demographic terms presented in this chapter, compare and contrast the populations of highly developed and less developed countries.

MATCHING Match the term in a growth rate equation with its definition. a.b e.K b.d f.N c.e g.r d.i -immigration rate

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?

MATCHING Match the term in a growth rate equation with its definition. a.b e.K b.d f.N c.e g.r d.i -the per capita rate at which organisms in a population die each year

Sketch an exponential growth curve with correctly labeled axes.Identify two organisms and the conditions under which they might demonstrate such growth.
