how does the energy of the sun become the energy of humans through the energy of green plants?

Because sun is needed for plants to go through photosynthesis, (this is what makes it turn green and grow). and so humans can eat it.. giving them the energy

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis. \n\n Photosynthesis takes place primarily in plant leaves, and little to none occurs in stems, etc. The parts of a typical leaf include the upper and lower epidermis, the mesophyll, the vascular bundle(s) (veins), and the stomates. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there. They serve primarily as protection for the rest of the leaf. The stomates are holes which occur primarily in the lower epidermis and are for air exchange: they let CO2 in and O2 out. The vascular bundles or veins in a leaf are part of the plant's transportation system, moving water and nutrients around the plant as needed. The mesophyll cells have chloroplasts and this is where photosynthesis occurs.The parts of a chloroplast include the outer and inner membranes, intermembrane space, stroma, and thylakoids stacked in grana. The chlorophyll is built into the membranes of the thylakoids. \n\nChlorophyll looks green because it absorbs red and blue light, making these colors unavailable to be seen by our eyes. It is the green light which is NOT absorbed that finally reaches our eyes, making chlorophyll appear green. However, it is the energy from the red and blue light that are absorbed that is, thereby, able to be used to do photosynthesis. The green light we can see is not/cannot be absorbed by the plant, and thus cannot be used to do photosynthesis. \n\nThe overall chemical reaction involved in photosynthesis is: 6CO2 + 6H2O (+ light energy)  C6H12O6 + 6O2. This is the source of the O2 we breathe, and thus, a significant factor in the concerns about deforestation.\n\n  \n\n\nThere are two parts to photosynthesis: \n\nThe light reaction happens in the thylakoid membrane and converts light energy to chemical energy. This chemical reaction must, therefore, take place in the light. Chlorophyll and several other pigments such as beta-carotene are organized in clusters in the thylakoid membrane and are involved in the light reaction. Each of these differently-colored pigments can absorb a slightly different color of light and pass its energy to the central chlorphyll molecule to do photosynthesis. The central part of the chemical structure of a chlorophyll molecule is a porphyrin ring, which consists of several fused rings of carbon and nitrogen with a magnesium ion in the center. \n The energy harvested via the light reaction is stored by forming a chemical called ATP (adenosine triphosphate), a compound used by cells for energy storage. This chemical is made of the nucleotide adenine bonded to a ribose sugar, and that is bonded to three phosphate groups. This molecule is very similar to the building blocks for our DNA. \nThe dark reaction takes place in the stroma within the chloroplast, and converts CO2 to sugar. This reaction doesn't directly need light in order to occur, but it does need the products of the light reaction (ATP and another chemical called NADPH). The dark reaction involves a cycle called the Calvin cycle in which CO2 and energy from ATP are used to form sugar. Actually, notice that the first product of photosynthesis is a three-carbon compound called glyceraldehyde 3-phosphate. Almost immediately, two of these join to form a glucose molecule. \n\nMost plants put CO2 directly into the Calvin cycle. Thus the first stable organic compound formed is the glyceraldehyde 3-phosphate. Since that molecule contains three carbon atoms, these plants are called C3 plants. For all plants, hot summer weather increases the amount of water that evaporates from the plant. Plants lessen the amount of water that evaporates

the roots absorbed minerals in the soil and the trunk/branches transport the nutrients to the leaves which manufature the plant food through a proccess called photosynthesis by the action of the chlorophyl which is the green color of the leaves, and the sun's ray

The sun is the earth's largest source of reliable energy.  Plants have green leaves that absorb and trap sunlight and convert that light into chemical energy; namely starches that other animals eat.\n\nThe sunlight is converted to starches by chlorophyll, a green substance in the leaves of green plants.  Carbon dioxide gas molecules (CO2) in our atmosphere is combined into sugar; sugar is combined into starches.  Wood is a form of starch called cellulose.\n\nSecondly, water is "split" (chopped into three pieces) releasing oxygen (gas) by photosynthesis.  So plants provide us oxygen by "splitting" water; and plants provide us sugar by "fixing" carbon dioxide.  We eat the plants or we animals that eat the plants.  This is how we get our energy.\n\nSo, cows are animals that eat grass; in so doing they gather sugar energy and live.  We eat cows, for example.  Or, certain insects eat plants; some fish eat those insects and then we eat the fish...so on and so forth.

Most life on Earth is powered by the Sun. Plants use Photosynthesis to make carbohydrates from the Sun. Animals eat Plants, we eat both plants and animals that eat plants. Therefore indirectly virtually all of our food energy comes from the Sun. Our Brain uses our food energy to operate. Therefore our brain is powered by the Sun.

plants use the sunlight to turn nutrients into sugars to feed the plant they also take the toxins away from the plant when they go brown and drop off. Carbon dioxide and oxygen are released from them.

Because chlorophyll is green.

Plants use solar energy to make their food by photosynthesis. They store the sun's energy in the form of carbohydrates.\n\nSolar cells work on fuel cells where they convert the sun's light energy to chemical energy which is to be changed into electrical energy at a future date.

Solar Power harnesses the energy of the sun to turn water into high pressure steam. The sun gives panels which heat the water kinetic energy to affect the interaction energy of the water (like how you get a sunburn). The steam rotates a turbine to generate power.

Process by which green plants and certain other organisms transform light into chemical energy. In green plants, light energy is captured by chlorophyll in the chloroplasts of the leaves and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds (simple and complex sugars) that are the basis of both plant and animal life. Photosynthesis consists of a number of photochemical and enzymatic reactions. It occurs in two stages. During the light-dependent stage (light reaction), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules. Oxygen, released as a by-product, passes into the atmosphere through pores in the leaves. NADPH and ATP drive the second stage, the dark reaction (or Calvin cycle, discovered by Melvin Calvin), which does not require light. During this stage glucose is generated using atmospheric carbon dioxide. Photosynthesis is crucial for maintaining life on Earth; if it ceased, there would soon be little food or other organic matter on the planet, and most types of organisms would disappear.\n\n\n\n    6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O\n\n    Carbon Dioxide + Water + Light energy → Glucose + Oxygen + Water
