Unit 2 The Living World: Biodiversity

Describe the amount of diverse types of species in one area...

• genetic diversity

• species diversity

• habitat diversity

What advantage do generalist species have in habitats that are constantly changing?

• They can easily switch their diet to a new food source

• They have a broad range of tolerance

• They are less likely to become extinct

• They are highly competitive and invasive

The limits to the abiotic conditions that a species can tolerate

• range of tolerance

• distribution

• realized niche

• fundamental niche

A reduction in the genetic diversity of a population caused by a reduction in its size.

• genetic drift

• gene flow

• bottleneck effect

• founder effect

This hypothesis says that intermediate disturbances—not too big and not too little—are ideal.

• build or rebuild soils

• Long Disturbance Hypothesis

• Intermediate Disturbance Hypothesis

• Small Disturbance Hypothesis

The number of species in a community...

• species richness

• species evenness

Ecosystems never change.

• True

• False

What advantage do specialist species have in habitats that remain constant?

• They can easily switch their diet to a new food source

• They have a broad range of tolerance

• They are less likely to become extinct

• They are highly competitive and invasive

Examples of this ecosystem service include regulating environmental conditions such as nutrient cycling and removing carbon from the atmosphere giving us more time to address climate change.

• provisioning

• regulating

• cultural

• supporting

The number of species in a given area

• species richness

• evolution

• species evenness

• phylogeny
