Question

Watch this video about life and the second law of thermodynamics. In a meadow, grasshoppers eat grass for energy. Birds eat the grasshoppers. Use the laws of thermodynamics to explain how energy from the sun is transformed and passed from one organism to another, to eventually power the muscles and nerves that the birds use to fly.

Answer 1

Energy is never lost or gained. It always transforms from one form to the other. Grass transforms radiant energy from the Sun into chemical energy so the grass can grow. Grasshoppers consume the chemical energy inside the grass. Birds consume the grasshoppers. They use some of the chemical energy obtained from the grasshoppers to send signals down their nerves, which requires electrical energy. These signals allow their muscles to move. As the birds fly, they use some of the chemical energy to power their flight. The breakdown of these biomolecules releases heat energy.

Step-by-step explanation:

Answer 2

Answer: The first law of thermodynamics establishes that energy cannot be created neither destroyed.

Step-by-step explanation:

So the grasshopers eat the grass to gain energy and then the birds eat the grasshopers to gain energy as well so by doing that they are just passing the energy to one another to power muscles and other body parts which follows the laws of thermodynamics that energy is not created but transfered from one system to another.
