The wood is made of organic carbon compounds produced when the tree grew, using carbon from the carbon dioxide CO2 in the atmosphere and energy from the Sun's light to split the carbon from the oxygen.
When the wood is burnt the carbon is recombined with more oxygen from the atmosphere to produce more CO2, and the original energy which came from the Sun is then released as heat.

What is the starting energy of a wood on a log fire?
It is the release of the chemical energy stored in the wood - however remember this chemical energy was originally trapped form the sunlight as the tree grew, so the ultimate source of the energy is the Sun.
Where does energy originally come from?
Energy is stored in every particle of matter in the universe. It just exists. It can neither be created nor destroyed.
What does biamass energy come from?
biomass is the recieving of energy from burning natural resources such as wood, leaves, crops, shrubbery, or other tinders.
How does the energy from a wood fire actually come from the sun?
light (sun) ----> photosynthesis (chemical energy) mechanical energy ----> cut down the tree work ----> move the tree store chemical energy from sun ----> light so basically photosynthesis gives the tree chemical energy, and when it is burned, the chemical energy is released causing light.
Wood in a fireplace or the ashes in the fireplace after the wood burns has more potential energy?
Wood in a fireplace. When woods burns it gives of heat, a form of energy. Thus the wood has more potential energy.
What type of energy was originally stored in wood?
Chemical energy.
Does geothermal energy originally come from the sun?
No it doesn't because geothermal energy originally comes from the ground!
Where does hydroelectric energy come from?
it comes from the sea or rivers originally.
Did wind originally come from the sun energy?
wind does originally come from the sun the sun heats the earth the heated earth causes wind
Where does the energy from coal originally come from?
the energy that is released when coal was at one time sunlight energy shining on plants.
Where does hydroelectric power energy come from?
it comes from the sea or rivers originally.
Where did the energy in the rice originally come from?
sun
How does photosynthesis produse biomass?
Biomass fuels come from living things. Wood is a biomass fuel. As long as we continue to plant new trees to replace those cut down, we will always have wood to burn. Just as with the fossil fuels, the energy stored in biomass fuels came originally from the Sun.
Where does the energy glucose come from originally?
It originally came from the sun and was stored in chemical bonds by plants during photosynthesis.
Where does the energy in the glucose originally come from?
It originally came from the sun and was stored in chemical bonds by plants during photosynthesis.
What is the starting energy of a wood on a log fire?
It is the release of the chemical energy stored in the wood - however remember this chemical energy was originally trapped form the sunlight as the tree grew, so the ultimate source of the energy is the Sun.
Where does all energy in a ecosystem originally come from?
All energy in any ecosystem originally comes from the sun. the energy is then passed on to the producers. including plants, trees, and anything else that uses photosynthesis.
