    All energy on Earth comes from the sun, including energy from the Earth's interior. And now the scholars are wrong about radioactive energy. The only energy on the earth** is solar energy, and a part of the solar energy is converted into the earth's internal energy.

    The Earth revolves around the Sun, why? The Earth vibrates in the elastic web of space, and this vibration can neither get close to nor far from the Sun. The elasticity of the earth's surface materials is different, such as continents and oceans, so the force imbalance between the earth and the surrounding space dark matter will inevitably produce the earth's rotation.

    The rotation of the Earth inevitably squeezes one side of the dark matter, and the other side of the dark matter produces a reaction force that causes the Earth to revolve around the Sun.

    The vast majority of the energy on Earth is greater than that of the Sun. The sun is the mother of all things, the "source" of energy, it provides the earth with a huge amount of energy, energy in the form of electromagnetic waves to radiate around, this phenomenon is called solar radiation.

    Earth's energy** compositionAccording to Einstein's mass-energy equation, processes such as the collapse of matter will lose mass and release energy, and some processes will release gravitational potential energy (potential energy is equivalent to stored energy). The earth's energy includes solar energy and energy provided by the earth itself, such as heat energy produced by the decay of radioactive elements.

    Most people accept that the universe is from the beginning, and then the universe begins to produce various elements and substances, and this process can release huge energy.

    We know that the celestial bodies in this universe have a relatively stable operating system. For example, the earth, where we humans live, operates in the solar system. Then the solar system operates in the Milky Way system.

    Above the Milky Way, there are also supergalaxies. The operating system of these stars can be said to be one after the other. And the earth where we humans live can be said to be a very small link in this big system.

    That is, in this link of planets and moons, but it is on planets that life is most likely to appear. Why is life on Earth? Just because of these two special conditions.

    Just like our earth, there is a lot of life. Because the energy on the stars is too high, but not all planets will have life. There are certain conditions.

    This generally depends on whether there is a planet at a moderate distance and rich in resources at the time of the formation of the star system. In our solar system, the Earth appeared. And in the solar system, there are some special cases that are simply ingenious.

    So the first thing to talk about is the distance between our earth and the sun. The position of our earth in the solar system can be said to be perfect. It's not too far from the sun, it's not too close.

    Because if our earth is too far away from the sun, then when the sun transfers heat to the earth, the earth's atmosphere will block most of the heat. At this time, the overall temperature of the earth will become very low, and there will be no way to see so many organisms now. So if the earth and the sun are too close, the sun will give too much heat to the earth.

    The Earth, and the atmosphere can't withstand too much heat, will be blown away by the solar wind, and the end result of the Earth will be as desolate as Venus now. So now this position, is just right.

    And what we know is that the earth has such a powerful atmosphere, but the solar wind can't blow it away. It's because at the poles of the earth, there is a very strong magnetic field. Our earth's atmosphere is left above the earth by this powerful magnetic field.

    However, a planet with such a strong magnetic field as the Earth is difficult to find within a 1,000-light-year radius of our Earth. So what is the magical power of this magnetic field? This magnetic field is absorbing the Earth's atmosphere and weakening the sun's heat.

    This magnetic field can also resist the radiation from the universe, and you must know that the radiation in the universe is very harmful to our earth. And it is precisely because of the existence of this magnetic field that the creatures on our earth have a good living environment.

    So the Earth is a very special existence in the solar system, or maybe in this galaxy. It is also normal for life to appear.

    Sun. Because the energy of food is ultimately also the sun. Food is divided into plants and animals.

    Let's talk about plants first: plants are stupid, and photosynthesis must rely on the sun; Let's talk about animals: animals are vegetarian and carnivorous.

    1.Vegetarian, then its food is plants, and the energy of plants ultimately comes from the sun, as mentioned above; 2.Carnivorous, its food is meat, that is, animals (including vegetarian animals and some vulnerable carnivores), and in the final analysis, the ultimate energy** still comes from the sun.

    Why is the sun the root of the energy required for life on Earth?

    Green plant photosynthesis completes two transformations, one transformation is to convert inorganic matter into organic matter, part of it is used to build the plant itself, part of it is used to provide food for other organisms**, and at the same time release oxygen for biological respiration and utilization The other transformation is energy conversion, in this process, green plants project part of the radiation energy projected by the sun on the earth's surface, which is converted into chemical energy stored in organic matter The energy stored through photosynthesis is almost the initial source of energy required for the life activities of all living beings at this stageAbout 90% of the power people need is obtained by relying on coal, oil, natural gas, peat and firewood, and all of the above power resources are accumulated from the photosynthesis of green plants in ancient times or today

    There are two types of energy on Earth that can support life activities, one is energy from outside the Earth, and the other comes from the chemical reactions of matter inside the Earth.

    Extended information: The sun is the most important energy on the earth**, it shines on the earth, so that the earth we live on is vibrant, and all things are prosperous. The direct users of sunlight are green plants that have lived and multiplied on the earth for more than 2 billion years.

    These green beings, some of them enormous, form lush forests on the earth's surface; Some are tiny, swimming in the translucent layers of the blue ocean. Their common feature is their ability to convert solar energy into chemical energy and produce organic matter through photosynthesis. This illuminates the fact that some of the greenery can be eaten by the animals of the planet and form the basis of the planet's food chain.

    We can imagine that if the earth loses the sunlight, the green plants will die due to the inability to photosynthesize, and the animals will disappear due to the lack of food and lead, and the whole earth will be a lifeless and lifeless scene. From this point of view, "everything grows on the sun" seems to be the unbreakable "golden rule" of nature! But is that really the case?

    Isn't it true that creatures in the deep sea can grow without sunlight?

    In fact, there are two kinds of energy on the earth that can support life activities. One is energy from outside the earth, which is solar energy. They reach the earth in the form of sunlight, and the growth of green plants on the earth depends on this energy.

    Another type of energy that supports life comes from the Earth's interior. This energy is produced by the chemical reactions of matter inside the Earth, and can also be absorbed and utilized by life.

    In the vicinity of deep-sea hydrothermal vents and cold seep vents, there are a large number of microorganisms that can capture energy from chemical reactions, and scientists call them chemoautotrophic microorganisms. Some of them prefer to "eat" methane, some prefer to "eat" hydrogen, and some prefer metal ions. Don't underestimate these quirks of microbes on the seabed, they are the secret of microbes that fill their stomachs and thrive!

    The abundance of chemoautotrophic microorganisms provides ample food for deep-sea animals**, resulting in unique biomes in the deep sea that do not depend on sunlight at all. <>

    The three major energy-producing nutrients (protein. fat, carbohydrates), so today I will share with you the energy in our human body.

    Human body energy is in the process of life activities, all life activities need energy, these energy is mainly food. Carbohydrates, fats, and proteins are oxidized in the body to release energy. The three are collectively referred to as "energy nutrients" or "calorific substances".

    Cereals and potatoes have more carbohydrates and are the most economical in terms of dietary capacity**; Oil crops are rich in fat; Animal foods generally contain more fat and protein than plant foods; The exception is soybeans and hard fruits, which are rich in oils and proteins. Vegetables and fruits are generally found in smaller amounts.

    Energy units. In the study of local metabolism of human experts, the traditional unit of energy is the kcal, also known as kilocalorie (kcal). The amount of energy (heat) required to heat 1 liter from 15°C to 16°C is called 1kcal.

    At present, the internationally accepted units of energy are joules (J), kilojoules (kj) and megajoules (mj). The conversion of the energy units of the two bi brothers is as follows:

    1kcal=,1kj=,1000kcal=,1mj=239kcal

    What is the ** of all the energy on the ground object?

    1.Sun. 2.Water.

    Correct answer: Sun.

    Solar energy is produced by the fusion of hydrogen atoms inside the sun to release a huge amount of nuclear energy, and the radiation of the sun is the hidden energy of the ballast. The vast majority of the energy required by humans comes directly or indirectly from the sun.

    Therefore, the answer is: because in the process of photosynthesis, green plants convert a part of the radiant energy projected by the sun on the earth's surface into chemical energy stored in organic matter The energy stored through photosynthesis is the initial source of energy required for the life activities of all living organisms At this stage, about 90% of the power required by people is obtained by relying on coal, oil, natural gas, peat and fuelwood, and all these power resources are accumulated from the photosynthesis of green plants in ancient times or today Therefore, the root of the energy required for life activities on earth is the sun
