Mangrove swamp can be found
- on a seashore with flat terrains
-
where a river meets the sea
- on a mud flat near the sea
- where two rivers meet
The correct answer is: B
Explanation
The correct answer is B - Where a river meets the sea.
Mangrove swamps are coastal ecosystems found in tropical and subtropical regions, typically where freshwater rivers meet the salty ocean. This unique environment, known as an estuary, provides a mixture of fresh and saltwater, creating a habitat for mangrove plants and a diverse array of wildlife.
Mangrove swamps thrive in these areas because:
- The river brings nutrient-rich sediment and freshwater, which supports plant growth.
- The ocean's tides and waves help distribute seeds, sediments, and nutrients.
- The mixture of fresh and saltwater creates a dynamic environment that supports a wide range of plant and animal species.
The other options are not correct because:
A. While mangroves can grow on flat terrains, they are not exclusive to these areas.
C. Mangroves can grow on mudflats, but this is not the primary location where mangrove swamps are found.
D. Mangrove swamps are not typically found where two rivers meet, as this would not provide the necessary mixture of fresh and saltwater.
