20. Sorting Out Species
Invasive Species - An invasive species is a species that is not native to a specific location, and which has a tendency to spread to a degree believed to cause damage to the ecosystem, human economy or human health eg.'s
Endangered Species - a species that is seriously at risk of extinction. eg.'s
Indicator Species - An indicator species is an organism whose presence or absence reflects a specific environmental condition. Indicator species can signal a change in the condition of a particular ecosystem, and thus may be used to diagnose the health of an ecosystem. eg.'s
Keystone Species - a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically. eg.'s
