← Earth & Natural SystemsWhat happens to the sediment composition of a coastal mangrove forest when there's an increase in the rate of root pneumatophore growth?
A)Increased erosion by tidal action
B)Increased fine sediment accumulation✓
C)Decreased organic matter deposition
D)Reduced nutrient availability to roots
💡 Explanation
Increased pneumatophore growth enhances sediment trapping within the mangrove forest floor because the complex root structures slow water flow, promoting the deposition of fine sediments. Therefore, fine sediment accumulates, rather than coarser sediments, due to reduced flow energy.
