Riparian foliage
a. provides shade and shelter
b. increases photosynthesis of aquatic plants
c. limits the organic matter present in rivers and streams
d. all of the above

The correct answer will be option-A

Explanation:

Riparian foliage represents the herbs, shrubs and trees growing near the bank of a river or at the interface between the land and the river stream. The riparian zones are mostly composed of the hydrophilic plants which either grow in the water or favor water for their growth.

The riparian foliage plays an important role in maintaining the ecosystem as they enable riparian organism and aquatic organisms to move along the riparian zone. They provide shelter to this wildlife habitat and shade to wildlife corridors.

Thus, option-A is the correct answer.
