These organs are believed to have been in use in the past lives but as the species adapts to new forms of life and lifestyle,the vestige organs becomes obsolete,but are not removed by the body. An example of vestige organs in human being are the appendix,tail bone,and mammalian grands in men.

Answer:
Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. The heat you feel in your body is the suns energy entering your body from the energy transfers that happen when you move.
Explanation:
Most of the energy that passes through the upper atmosphere and reaches Earth's surface is in two forms, visible and infrared light. The heat you feel in your body results from the energy transfers that happen when you move. When you sweat, your body expends energy to cool itself down. A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers.
