sun
The Sun is Earth's primary source of light energy. It emits light in the form of electromagnetic radiation that reaches Earth and provides energy for various processes such as photosynthesis and heating the planet.
The Sun is Earth's primary external energy source. Solar radiation emitted by the Sun provides heat and light energy to sustain life on Earth through a process called photosynthesis.
The primary source of Earth's energy is the sun. This energy is called solar energy, which is harnessed through various processes like photosynthesis, wind energy, and solar panels.
The Sun is Earth's primary source of light energy. The Sun emits electromagnetic radiation, including visible light, which provides energy for photosynthesis and powers many processes on Earth.
The sun is the major external source of energy.
Carbohydrates are the body's primary and immediate source of energy.
electron
The term clean source of energy refers to only primary energy sources as wind or solar energy. Electricity, by definition, is not a primary energy source. It is a secondary energy source that is could be produced by a clean energy source as wind or any renewable primary energy source or produced by fossil energy source as oil, natural gas, or coal.
Carbohydrates are the primary energy source for herbivores (cows, horses, etc.). Proteins are the primary energy source for carnivores (dogs, cats, etc.).
Carbohydrates are the body's primary and immediate source of energy.
The sun is the initial (primary) energy source for life. Ingestion and digestion of a food source is an animal's primary source of energy.
