Understanding Biogeography and Ecology

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

What is the primary factor that influences species richness on islands according to the theory of island biogeography?

Back

The size of the island.

Front

In a graph showing the relationship between island size and species extinction rate, what trend would you expect to see?

Back

Extinction rate decreases with island size.

Front

Which of the following is an example of ecological tolerance?

Back

A plant species that can only survive in a narrow range of temperatures.

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 are affected by the size of the island and its distance from the mainland.

Front

What is species richness?

Back

Species richness refers to the number of different species represented in a given ecological community.

Front

How does island size affect species extinction rates?

Back

Larger islands tend to have lower extinction rates due to more available resources and habitats.

Front

What role does distance from the mainland play in species diversity on islands?

Back

Islands that are closer to the mainland typically have higher species diversity due to easier access for species migration.
