Carbon Cycle LS2-5
| Term | Definition |
|---|---|
| Acidification | The process of increasing the acidity of a substance or environment, often referring to the ocean's pH level decreasing due to the absorption of carbon dioxide. |
| Atmosphere | The gaseous layer surrounding a planet, such as Earth, that is held in place by gravity. |
| Autotroph | An organism that can produce its own food using energy from sunlight or inorganic substances. Examples include plants and algae. |
| Biomass | The total mass of living organisms in a given area or ecosystem, often referring to plant material that can be used as a renewable energy source. |
| Biosphere | The regions of the Earth's surface, atmosphere, and hydrosphere where living organisms exist. |
| Carbon cycle | The continuous movement of carbon through Earth's atmosphere, biosphere, geosphere, and hydrosphere, involving processes such as photosynthesis, respiration, and decomposition. |
| Carbon dioxide (CO2) | Inorganic carbon form found in the atmosphere |
| Carbon fixation | The process by which atmospheric carbon dioxide is converted into organic compounds by autotrophic organisms during photosynthesis. |
| Carbon reservoir | A place or medium that stores carbon, such as the atmosphere, oceans, or fossil fuels. |
| Carbon sink | A natural or artificial reservoir that absorbs and stores more carbon than it releases, helping to reduce the concentration of carbon dioxide in the atmosphere. |
| Chloroplast | A specialized organelle found in plant cells where photosynthesis takes place, containing chlorophyll and other pigments. |
| Climate change | Long-term shifts in temperature, precipitation patterns, and other aspects of the Earth's climate system, primarily caused by human activities. |
| Combustion | The process of burning a fuel, releasing heat, light, and various combustion products, such as carbon dioxide and water vapor. |
| Consumers | Organisms that obtain energy by consuming other organisms or organic matter. They are also known as heterotrophs and include animals and fungi. |
| Decomposition | The breakdown of organic matter into simpler forms, usually carried out by bacteria, fungi, and other decomposers. |
| Energy | The capacity to do work or produce heat. |
| Fossil fuel | A natural fuel formed from the remains of living organisms, such as coal, oil, or natural gas. |
| Geosphere | The solid part of the Earth, including the rocks, minerals, and landforms. |
| Glucose/sugar | Organic carbon that is created through photosynthesis |
| Greenhouse gas | A gas that traps heat in the Earth's atmosphere, contributing to the greenhouse effect. |
| Heterotroph | An organism that obtains its energy by consuming other organisms or organic matter. |
| Hydrocarbons | Organic compounds composed of hydrogen and carbon atoms, commonly found in fossil fuels. |
| Hydrosphere | The water on or near the Earth's surface, including oceans, lakes, rivers, and groundwater. |
| Methane | A greenhouse gas and the main component of natural gas. |
| Microbes | Microscopic organisms, such as bacteria or viruses. |
| Mitochondrion | An organelle in cells that generates energy through cellular respiration. |
| Molecule | A group of atoms bonded together, representing the smallest unit of a chemical compound. |
| Ocean uptake | The process by which the ocean absorbs or takes in substances, such as gasses or nutrients. |
| Organic matter | Material derived from living organisms, often found in soil or as decaying plant and animal remains. |
| Photosynthesis | The process by which green plants and some other organisms convert light energy into chemical energy, producing oxygen and glucose. |
| Phytoplankton | Microscopic aquatic organisms, such as algae, that carry out photosynthesis and form the base of the food chain in aquatic ecosystems. |
| Producers | Organisms, including plants and algae, that can produce their own food through photosynthesis or chemosynthesis. |
| Reaction | A process that involves a chemical change or transformation, often resulting in the formation of new substances. |
| Respiration | The process by which organisms convert oxygen and glucose into carbon dioxide, water, and energy, typically through cellular respiration. |
| Sedimentation | The settling or deposition of particles, such as mud, sand, or silt, in a liquid or on a surface. |
| Transpiration | The process by which plants release water vapor into the atmosphere through their leaves. |
