Because it gives energy to the plants, using pphotosynthisis. Herbivors then eat these plants, then meat eaters eat these. They each get the energy from the plants. This goes on and on. This is why more and more food needs to be eaten each level you increase in the food chain, because each time some energy is lost, the animal needs to eat more to get the same amount of energy.
The ultimate source of energy for all organisms on Earth is the Sun. Through the process of photosynthesis, plants and other photosynthetic organisms convert sunlight into chemical energy that can be used by other organisms in the food chain.
Plants get food from it and we get heat and light.The sun is also our closest star.There might be other huge sources of energy out there,but none ultimate to us.
For us here on Earth, the prime source of energy is the Sun.
The Sun
The Sun produces its energy - the heat and light that reaches us from the Sun - from nuclear fusion. Specifically, it converts hydrogen to helium.
Mainly, it is important for us, as our main energy source.
No. At least, sound and electricity doesn't reach us directly from the Sun. What we receive is the sunlight - light energy.
The sun in the main source of energy, providing heat-for animals, solar powes, ect...., which then turns to energy. We then use energy for electricity, which powers alsost all of our technology. :)
Glucose is considered a very important molecule for living beings because it provides us energy & we use most of the energy in the form of glucose(the ultimate source of energy. bhuvan sorout
The sun is a source of energy but we cant use it for ourselves other than staying warm. the main source of energy for most living things are nucleic acids, they send chemical reactions to the body that make us who we are -Edited by Jordan R.
Because the sun gives of heat which keeps our muscles warm, which lets us use energy to do stuff. and all the other necesities..
The Sun is the ultimate source of energy. It provides solar energy which is responsible for light as well as heat. Hence, no other body can give more heat than the sun.
