Answer to Question 1

ANS: F
Terrestrial communities evolve at faster rates than marine communities. Environmental factors do not
change as quickly in the ocean as they do on land. Information can be found in the section Marine
Communities Change as Time Passes.

Answer to Question 2

ANS: F
The conditions of the intertidal are intensified in the sandy, loose substrate. The organisms living in
high energy sand and cobble beaches can be found in the most hostile and dangerous environments.
Information can be found in the section Examples of Marine Communities.
