Looking at it very simplistically, the sun contains an enormous amount of hydrogen inside which through the nuclear fission process produces helium. The process of fission (combing of 2 hydrogen atoms into 1 helium atom) releases tremendous amount of energy. The energy is equivalent to the mass that is lost in the fission process.
The sun produce light and nuclear energy
the energy sun and stars produce is fusion.
Sun energy can be used as a primary energy source to produce electricity which can be used in all end-user energy application.
satellites produce energy by the sun
The sun because it's hot and humans turn it into energy
No, the sun's energy comes from nuclear fusion reactions
Technically no. It does, however, produce the vast bulk of it.
The sun is the source of all energy in a food web. The primary producers - plants - use the sun's energy to produce organic compounds. Some producers eg micro-organism use inorganic chemical reactions to produce energy
No, not all organisms get their energy directly from the sun. While organisms like plants use sunlight to produce energy through photosynthesis, other organisms like animals get their energy by consuming plants or other animals. This creates a food chain where energy is transferred from one organism to another.
Primary producers use the light and energy from the sun to produce energy. The primary producers sit on top of the trophic level and are mainly plants and algae.
The Sun.
...The sun. That's why their called producers. Because they PRODUCE their own energy using the sun...
