Explain the energy transformation that occurs when a person exercises. (4 points) Magnetic energy transforms into mechanical energy. Electrical energy transforms into mechanical energy. Mechanical energy transforms into thermal energy. Thermal energy transforms into electrical energy.

Mechanical to Thermal

Explanation:

When you exercise, you are using mechanical energy to get your body moving. When you start sweating, your body is heating up, so it is thermal energy.

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 

the answer would be   10%
