Consider the following statements about an estuary :
1. An estuary is the place where the river fresh water meets with ocean water.
2. This area is highly productive.
3. This area is highly unproductive.
Which of the above statements is/are true ?
Answer: C
Statements 1 and 2 are true, so the answer is 1 and 2 only.
An estuary is the partly enclosed coastal water body where a river's fresh water mixes with sea water (1). Rivers bring in nutrients and sediment while tides keep the water mixed, so estuaries rank among the most productive ecosystems on earth. They support mangroves and salt marshes, act as nurseries for fish and shellfish, and feed large bird populations (2).
Statement 3 contradicts statement 2; an estuary is highly productive, not unproductive. That rules out '3 only', and '1 only' and '2 only' each leave out a true statement.
