Fabric is what something is made from, especially clothing. Silk is a common fabric, but you can also talk about the fabric of society.. The most common use of fabric is for clothes: for example, denim is the fabric used to make jeans. All clothes are made of some type or combination of fabrics. The basic structure of a building or a vehicle can also be called fabric, and non-physical things can be represented as fabric too. Metaphorically, you could say honesty is part of the fabric of friendship, or love is part of the fabric of family.
Together, photosynthesis and chemosynthesis fuel all life on Earth. Photosynthesis occurs in plants and some bacteria, wherever there is sufficient sunlight â on land, in shallow water, even inside and below clear ice. All photosynthetic organisms use solar energy to turn carbon dioxide and water into sugar and oxygen. There is only one photosynthetic formula: CO2 + 6H2O -> C6H12O6 + 6O2. Chemosynthesis is the use of energy released by inorganic chemical reactions to produce food.
Humans harness energy conversion processes to provide energy services.Energy demand is derived from preferences for energy services and depends on properties ofconversion technologies and costs. Energy commodities are economic substitutes.Energyresources are depletable or renewable and storable or non-storable.ire, providing heat and light, is. a process by which chemical energy stored in the fuel, say, wood, is converted to thermal. energy and radiant energy. Chemical energy stored in wood is the result of photosynthesis, whereby plants convert energy in sunlight to chemical energy, stored in the plant material.
