Topic 2.1 & 2.2

All of the following are ways to measure biodiversity except

• Genetic

• Species

• Climate

• Habitat

Ecosystems with more biodiversity will be affected more by natural disturbances.

• True

• False

More habitat diversity = less ecosystem services and functions.

• True

• False

A population bottleneck

• occurs when a significant increase in the population size reduces genetic variation

• causes populations to grow larger over time

• occurs when a population goes from large to small due to a natural or human event, reducing genetic diversity

• increases genetic variation within a population

The ability for an ecosystem to withstand some type of disturbance without the flow of matter and energy being affected can be described as ecosystem __________________

• Resistance

• Resilience

The ability for an ecosystem to return to its previous state of cycling matter and energy after a natural disturbance can be described as ecosystem __________________

• Resistance

• Resilience

Species that have specific types of environments they can survive in

• Generalist

• Specialist

Species that have a broad range of environments they can survive in

• Generalist

• Specialist

Species that eats a variety of food

• Generalist

• Specialist

Species that do not adapt easily

• Generalist

• Specialist
