Cycling of Matter+Energy Transformatio+Photosynthesis

Biomass Material from living or recently living organisms composed of a mixture of organic molecules containing hydrogen, carbon, often nitrogen, and small quantities of other atoms.
Decay The natural process or result of being slowly broken down or decomposed, chiefly by bacteria and fungi.
Decomposers Organisms such as bacteria and fungi that break down the remains of dead plants and animals, without need for internal digestion.
Bacteria A highly diverse group of single-celled, prokaryotic organisms.
Fungi Microorganisms important as decomposers; widely distributed and can break down just about any type of organic matter.
Microorganisms Organisms too small to be seen by the unaided human eye, such as bacteria and fungi.
Detritivore An organism that feeds on and breaks down dead plant or animal matter; includes decomposers (bacteria and fungi) as well as larger organisms such as insects and worms, serving as primary consumers in a food chain.
Water Cycle The movement of water through the atmosphere, the ground, bodies of water, and living things; the continuous movement of water above, on, and below Earth’s surface.
Carbon Cycle The cycle by which carbon is exchanged among the soil, biosphere, lithosphere, hydrosphere, and atmosphere of the Earth.
Nitrogen Cycle The process by which nitrogen is converted between its various chemical forms as it is exchanged among the soil, biosphere, lithosphere, and atmosphere of the Earth.
Energy Transformation The change of energy from one form to another.
Chemical Energy Energy stored in chemical bonds and released through chemical reactions.
Digestion The process of breaking down food into component molecules that can be absorbed into the body and used for energy and nutrients.
Mechanical Energy The sum of the potential and kinetic energy of an object.
Thermal Energy The total kinetic (motion) energy of tiny particles that make up matter - the faster the particles move, the warmer the matter becomes.
Heat Energy transferred between two objects of different temperatures, moving continually in a predictable pattern from warmer site to cooler site until all sites have reached the same temperature.
Radiant Energy Energy from the sun that reaches earth as visible light, and ultraviolet and infrared (heat) radiation.
Photosynthesis A chemical reaction during which plants convert radiant energy from the Sun to chemical energy; the reaction converts carbon dioxide and water into sugar (glucose).
Chemical Reaction A process by which two or more chemical substances interact and are chemically changed, producing different chemical substances.
Reactants A substance that takes part in and undergoes change during a reaction.
Products A substance produced during a chemical reaction.
Glucose Simple carbohydrates; produced by photosynthesis and used to store energy and build structural molecules.
Atom The smallest particle of an element, made of electrons, protons, and neutrons.
Molecule The simplest unit of a chemical compound that can exist, formed when two or more atoms join together chemically.
