There are chemical reactions that only work in the presence of light. One of these is a rather complex reaction that combines carbon dioxide and water to form such things as simple sugars. To simplify:
12 CO2 + 11 H2O -> C12H22O11 + 12 O2
The reaction uses energy from light. A reverse reaction can be done, and uses the sugar and oxygen to give off energy. This is sort of thing is the basis of life. Notice that in storing energy, we are storing carbon and hydrogen.
The sugars do not last forever, as all carbon atoms have a tendency to break down. Sugars will turn into simple hydrocarbons over time, giving up the oxygen they hold, and taking on such forms as (for example) octane, which is C8H18. During the time the molecules decay, they are sometimes subducted into the earth's crust, forming coal and oil in the process.
So a chemical reaction that was fueled by light eventually causes a build up of underground carbon and oil.
Because almost all processes occurring on the surface of the earth rely on the sun as their ultimate source of energy. The only ones that don't are those that rely on geothermal energy.
Sun plays the source of energy in a food web.
It is the biotic source; input; energy
Sun is the source of heat and light energy. It provides energy on earth's surface.
Nuclear fusion in the Sun
the sun
The sun is the ultimate source of all energy in Earth's ecosystems.
the sun
In most food webs the Sun is the ultimate source of energy. Some food webs start with chemotrophs and in those cases the source of the energy are chemicals often from underwater volcanoes.
plants are not the ultimate source of energy. It is the sun which is the ultimate source of energy to this planet
The ultimate source of energy for plants is the sunlight which theycapture it from the sun. It is one of the main components ofphotosynthesis.
If we assume that petroleum was created from decaying plants, the ultimate energy source is the Sun's energy.If we assume that petroleum was created from decaying plants, the ultimate energy source is the Sun's energy.If we assume that petroleum was created from decaying plants, the ultimate energy source is the Sun's energy.If we assume that petroleum was created from decaying plants, the ultimate energy source is the Sun's energy.
The sun is the ultimate source of energy for almost all earth ecosystems.
The ultimate source of the energy driving it is that coming from the Sun.
the sun
solar energy coming from sun
water is ultimate source of energy or................................... . . . . . . . . . . . . . . . maybe is it sun i dont know either sun or water it's your own answer
