The sun
This is the thermal energy from sun.
Carbohydrates.
The most abundant organic compound on Earth is glucose and its polymers. This is a good thing, as organisms need glucose for energy.
Bacteria, the most numerous organisms on Earth , are unicellular organisms - just had this question on a homework
Carbohydrate
The source of energy for most organisms is chemical energy and sunlight.
The sun is the main source of energy on earth.

Most life on earth, gets there energy source from the sun, that is assuming that the majority of life on earth are autotrophs (plants). They get this energy by photosynthesising and getting a energy source called glucose, which is used in nearly all organisms on earth... they can then use glucose as a respiratory substrate, for respiration... Hope this helps :)

We get most of our energy from the Sun.

On Earth, the greatest source of thermal energy would be at the earth's core.
