Front

The study of the locations of organisms around the world is called________.

Back

Biogeography

Front

Which of the following best describes the concept of island biogeography?

Back

The study of the ecological and evolutionary processes that affect the species composition and diversity on islands.

Front

How might a graph depicting the relationship between island size and species diversity be used to make predictions?

Back

By estimating the number of species on a new island based on its size.

Front

Which of the following statements is true regarding the relationship between ecological tolerance and environmental changes?

Back

Species with narrow ecological tolerance are more vulnerable to environmental changes.

Front

In the context of island biogeography, what is the significance of the equilibrium point on a graph showing immigration and extinction rates?

Back

It represents the point where immigration and extinction rates are equal.

Front

Define biogeography.

Back

Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time.

Front

What is island biogeography theory?

Back

Island biogeography theory explains how species composition and diversity on islands are affected by immigration and extinction rates.

Front

What factors influence species diversity on islands?

Back

Factors include island size, distance from the mainland, and ecological conditions.

Front

Explain ecological tolerance.

Back

Ecological tolerance refers to the range of environmental conditions that a species can withstand.

Front

What is the relationship between island size and species diversity?

Back

Larger islands tend to support more species due to greater habitat diversity and resources.
