Artificial Selection

Mutation

Tragedy of the Commons

Biodiversity
A close relationship between two different species living together.
Symbiosis
A species that naturally occurs in a particular area without human introduction.
Native Species
Sea otters help control sea urchin populations, which helps protect kelp forests. Without the sea otters, there would be an abundance of sea urchins and they would eat all the kelp in the ecosystem. This would have a huge impact on other species that use the kelp for food and shelter. What are sea otters an example of?
Keystone Species

Natural Selection
The process in which humans choose organisms with desired traits to reproduce.
Artificial Selection

Tragedy of the Commons
