Q23.
Which of the following best explain(s) the rationale for protecting mangrove ecosystems in the context of climate resilience ? 1. Mangroves reduce tidal energy and store freshwater, making them ideal sites for paddy cultivation in saline estuarine belts. Their salt-sensitive roots filter seawater, making mangroves key to converting coastal land into freshwater aquaculture zones. 3. By withstanding tidal surges and offering biomass resources, mangroves function both as natural bio-shields and livelihood bases for rural communities. Select the answer using the code given below :
Answer
D
Explanation
Mangroves are salt-tolerant coastal ecosystems that dissipate wave and storm-surge energy, reduce erosion and provide livelihood resources such as fish, honey and biomass. They do not convert saline land into freshwater zones, and their roots are adapted to salinity rather than 'salt-sensitive'. Hence only statement 3.
