Which natural process is the main cause of the ocean currents shown?

The Coriolis Effect bounces ocean currents in the Southern Hemisphere to the left due to Earth's revolution because the current located in the Southern Hemisphere. The answer is convection. Ocean currents caused by forces acting upon this callous flow, such as wind, the Coriolis Effect, breaking waves, cabbing, and temperature and salinity differences.  

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
