fusion reaction of helium and hydrogen
by it self, they create & produce their own energy just like the sun
It depends. Most of the autotrophs you have seen are green plants and they ultimately get their energy from the sun through photosynthesis. In the oceans, around volcanic vents, entire ecosystems get their energy from organisms that absorb the dissolved chemicals for energy. These are chemoautotrophs or 'chemotrophs' for short.
The sun.
...The sun. That's why their called producers. Because they PRODUCE their own energy using the sun...
Sun energy can be used as a primary energy source to produce electricity which can be used in all end-user energy application.
Yes oak trees are producers, their source of energy is the sun and they produce their own food using the sunlight and water.
water is ultimate source of energy or................................... . . . . . . . . . . . . . . . maybe is it sun i dont know either sun or water it's your own answer
No, you cannot directly get energy from the moon. The moon does not produce its own energy source like the sun does through nuclear fusion. However, we can harness energy indirectly from the moon through tidal power generation.
The ultimate source of energy for everything on Earth is the Sun. Plants convert solar energy into chemical energy through photosynthesis, which is then transferred through the food chain to other organisms for their energy needs.
Nuclear fusion of hyrogen nuclei (protons) to produce helium
To my knowledge, the stars have their own energy and they will be generally surrounded by some planets. So SUN falls in this category. It has its own source of energy.
Energy from the sun makes the grass grow and that is what the cows feed on to produce milk.
