Answer to Question 1

ANS: C
Salt-tolerant plants in the estuary are able to grow very quickly. When they die, their decomposition
and the rapid turnover of nutrients become important in the ecosystem. This is a common
characteristic of estuaries. Information can be found in the section Marine Scientists Examples of
Marine Communities

Answer to Question 2

ANS: C
The high wave activity ensures a constructive and destructive balance in coral reefs. The waves move
nutrients and dissolved gasses with every pass towards the coral. Information can be found in the
section Examples of Marine Communities
