Chpt 4: Evolution & Biodiversity

The variety of Earth’s species

• Biological Evolution

• Habitat

• Native Species

• Biodiversity

A species that naturally lives and thrives in a particular ecosystem

• Biological Evolution

• Habitat

• Native Species

• Biodiversity

The place or type of ecosystem in which a species lives and obtains what it needs to survive

• Biological Evolution

• Habitat

• Native Species

• Biodiversity

Process by which Earth’s life forms change over time

• Biological Evolution

• Habitat

• Native Species

• Biodiversity

Large geographic region characterized by a distinct climate and mix of species

• Mutation

• Biome

• Genetic Engineering

Method used to alter an organism’s genetic material by adding, deleting, or changing segments of its DNA

• Mutation

• Biome

• Keystone Species

• Genetic Engineering

A species that has a large effect on the types and abundance of other species in an ecosystem

• Mutation

• Biome

• Keystone Species

• Genetic Engineering

Permanent change in the DNA sequence within a gene

• Genetic Engineering

The abundance and distribution of a species within an ecosystem

• Indicator Species

• Background Extinction Rate

• Species Diversity

• Generalist Species

• Biological Extinction

Species whose presence, absence, or abundance is linked to a  specific environmental condition and as a result is sensitive to environmental change
