Question

compare salt marshes and mangrove forests and explain why mangrove forests are such critical habitats on high energy coasts.

Explanation:

Salt marshes are dominated by salt - tolerant grasses and herbs, typically in temperate regions. Mangrove forests are composed of salt - adapted trees and shrubs, mainly in tropical and subtropical areas. On high - energy coasts, mangrove forests are critical as their complex root systems (e.g., prop roots, pneumatophores) can dissipate wave energy, reducing erosion. They also provide habitat for numerous species, contribute to nutrient cycling, and act as a buffer between land and sea.

Answer:

Salt marshes are grass/herb - dominated in temperate zones, while mangrove forests are tree/shrub - dominated in tropical/subtropical zones. Mangrove forests are critical on high - energy coasts due to their root systems' ability to reduce wave energy and erosion, provide habitat, and contribute to nutrient cycling.
