fats
During low-intensity activity, the major fuel used is fat. This differs from high-intensity activity, where the major fuel used is carbohydrates.
hot objects, i.e. incandescencereemission of absorbed light, i.e. fluorescence (immediate), phosphorescence (delayed)relaxation of excited electrons to lower energy levels in atoms, e.g. LEDs, neon lightstriboluminescenceetc.

A major result of prohibition during the 20s was an increase in gang activity.

These elements are transported by rivers to the sea. Another source is the volcanic activity.
Sun is the source of heat and light energy. It provides energy on earth's surface.

The nutrients stored in body cells and converted into the major fuel source for muscles are primarily carbohydrates, specifically glycogen, and fats. Glycogen is stored in the liver and muscle tissues, while fats are stored in adipose tissue. During physical activity, these nutrients are metabolized to provide energy, with glycogen being the preferred source for high-intensity exercise and fats being used more during prolonged, low-intensity activities.
It was a major producer of sugar.
