$2$. Mangrove plants cans survive high salinity, tidal extremes, strong wind velocity, highs temperature and Muddy aerobic soil.
Select the correct answer using the code given below.

• A. $1$ only
• B. $2$ only
• C. Both $1$ and $2$
• D. None of the above

Answer 1

Answer: (B)

$2$ only

Mangroves are salt tolerant forest ecosystems found mainly in the tropical and sub-tropical intertidal regions of the world. They encompass swamps, forest-land within, and the surrounding water bodies. It is a matter of great surprise that mangrove floral species can thrive luxuriantly in saline habitat (which is basically physiologically dry in nature) through orientation of their morphological, anatomical and physiological systems. Thus this vegetation is the most efficiently adapted biotic community in response to climate change induced sea level rise.

The mangroves exist under very hostile and inhospitable condition, as they have to encounter extreme salinities, tides, wind velocities, temperature and muddy anaerobic soils. They are highly adapted to coastal environment by having breathing roots, supporting roots, salt-excreting leaves and viviparous,

water-dispersed propagules. The muddy soil is not aerobic in nature.

So the correct option is '2 only'.
