Which biome-altering phenomenon arises when deforestation increases freshwater runoff into coastal mangrove forests?

A)Reduced species diversity due to salinity shock
B)Accelerated mangrove growth from nutrient import
C)Increased predation from oceanic predator intrusion
D)Reduced carbon sequestration from altered acidity

💡 Explanation

When deforestation increases freshwater runoff, reduced salinity tolerance caused by disrupted osmoregulation affects mangrove species, harming less tolerant species because mangrove roots encounter fluctuating water potentials, due to disrupted ionic balance. Therefore biodiversity decline results, rather than increased growth, predation change, or carbon sequestration reduction because other processes were not significantly impacted.
