Question 4

Vicariance

Answer 4

Separation of wide-spread species by barriers arising from changes to geology, climate or habitat

Question 5

Answer 7

A set of environmental conditions in which a species can have a positive population growth

Question 8

Competitive exclusion principle

Answer 8

Species that are too similar in resource use cannot coexist indefinitely
