What would happen if the sand dunes in an area were destroyed?

sand dunes protect inland areas from swells, tides, and winds, they must be protected and defended like national treasures. The ocean and the wind can have an unpredictable, destructive force on coastal regions

Explanation:

. A natural barrier to the destructive forces of wind and waves, sand dunes are our first line of defense against coastal storms and beach erosion. They absorb the impact of storm surge and high waves, preventing or delaying flooding of inland areas and damage to inland structures.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

idk im sorry.
