Does the sun have any characteristics of life?
Living things need food to grow, they move, respire, reproduce, excrete wastes from the body, respond to stimuli in the environment and have a definite life span. Water, sun, moon and stars do not show any of the above characteristics of living things. Hence, they are non-living things.
What is the role of Sun to the existence of living organism?
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

What are characteristic of life?
Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits.
What is the Sun’s characteristics?
The Sun is composed of about 75% hydrogen, 25% helium, and trace amounts of heavier elements. At its core, the Sun’s temperature reaches over 15 million K (27 million°F) and its pressure is over 200 billion times the pressure at Earth’s surface.
What is 3 Characteristics of the Sun?
The Sun consists of about 70% Hydrogen, 28% Helium and 2% of metals such as iron. Other characteristics are its rotation, temperature, and radiation.
What happens on the sun?
In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.
