Why sun is ultimate source of energy?
The sun is called the ultimate source of energy because: It is the primary source of energy for the earth. With the help of solar energy, all green plants(producers) produce food by the process of photosynthesis.
Why sun is called ultimate source?
The sun is called the ultimate source of energy because it is the source of almost all energise of the earth. -» Plants make food using sunlight, the food that we get from plants and animals also has its prime source as sunlight.
Why is the sun ultimate source of energy Class 7?
Ans: The solar energy is very important to carry out the process of photosynthesis, it is captured by the leaves and stored in the plant in the form of food. And this in turn use by other organism to get food to obtain energy Thus, we say that sun is the ultimate source of energy for all living organisms.
What is the ultimate source of sun?
The Sun is the Ultimate Source of Energy. Every morning the sun rises, bringing light and heat to the earth, and every evening it sets.
What is sun called as ultimate source of energy?
The sun is called the ultimate source of energy because it is the source of almost all energies of the earth. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis.
Why is ultimate source of energy?
The Sun is called the ultimate source of energy. Plants require sunlight, water, and CO2 for photosynthesis. Plants convert light energy from the sun into chemical energy which is in the form of food. The wind energy, tidal power, wave power depends on the sun. Hence sun called the ultimate source of energy.
What is called the ultimate source of energy?
Sun – The Ultimate Source Of Our Energy.
Is ultimate source of energy?
The Sun
The Sun is called the ultimate source of energy. Plants convert light energy from the sun into chemical energy which is in the form of food.
What is the source of energy in sun give example?
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom.
What is the Sun ultimate source of energy?
The Sun is an infinite (at least in terms of human time scales) and renewable source of energy which is also by far the most important source of energy for us. Primary productivity (photosynthesis) is driven by sunlight and all our fossil fuels are derived from plants which existed millions of years ago.
What is the main source of solar energy?
Answer: The main source of solar energy is the SUN. Energy is produced by nuclear fusion in the core region through a series of steps called the p–p (proton–proton) chain in the surface of the sun; this process converts hydrogen into helium and massive light and heat energies.
What type of energy comes from sun?
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
Why is the Sun called the ultimate source of energy?
-» The fossil fuels that we use in our daily life comes from dead plants and animals which again have their source as solar energy. Sun is the ultimate source of the because it provides energy in the form of light that helps the plants to make food and it is almost all the energies of the world that humans are also using .
Which is the primary source of energy on Earth?
The sun is considered the primary energy source since it is the source of nearly all the earth’s energy. Plants produce food using sunlight, and the food we get from plants and animals also has its primary sunlight source. The fossil fuels we use in our everyday lives come from dead plants and animals that have their origins as solar energy again.
Where does all the energy in the world come from?
4. Right now, much human activity uses energy from fossil fuels such as coal, oil, and natural gas. These energy sources are created over very long periods of time from decayed and fossilized living matter (animals and plants), and the energy in that living matter originally came from the sun through photosynthesis.
