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.

The sun provides energy through sunlight, which plants use in photosynthesis to convert carbon dioxide and water into glucose (sugar). This glucose is then used as a source of energy for the plant's growth and maintenance. Ultimately, all food chains begin with this process, as animals consume plants or other animals that have consumed plants.

The ultimate source of solar radiation is?

The ultimate source of solar radiation is nuclear fusion that occurs in the core of the sun. This process releases energy in the form of electromagnetic radiation, which includes sunlight.


Why is the sun the most important source of energy?

The sun is the most important source of energy on Earth because it provides the majority of the energy needed for life through solar radiation. This solar energy is essential for photosynthesis to occur in plants, which is the foundation of the food chain. Additionally, solar energy is harnessed for various renewable energy technologies to generate electricity and heat.


What role does the sun play in a food web?

The sun is the primary source of energy in most ecosystems. Through photosynthesis, producers like plants and algae convert sunlight into chemical energy, which is then consumed by herbivores, carnivores, and other organisms in the food web. Without the sun, the production of energy-rich organic compounds at the base of the food web would not be possible.


What is the primary source of energy in a food web?

The primary source of energy in a food web is the sun. Plants and algae use sunlight to undergo photosynthesis and convert it into chemical energy, which is then passed on to consumers in the food chain.


What is the sun in the food chain?

The sun is the primary source of energy for most ecosystems, providing sunlight for photosynthesis. This energy is then transferred through the food chain as plants convert sunlight into chemical energy, which is consumed by herbivores and then passed on to carnivores. In this way, the sun is the foundational energy input for almost all life on Earth.
