|---|---|
| Economic System | Network of people, institutions, and commercial interests involved in the production, distribution, and consumption of goods and services. |
| Sustainable Development | Meets needs of present generation without reducing the ability of future generations to meet their needs. |
| Ecosystem | All of the organisms living in a particular place and their interactions with each other and with the local climate and geology. |
| Economics | Social science concerned with production, distribution, and consumption of goods and services as well as the theory and management of economic systems. |
| Energy | The capacity to do work. |
| Work | Description of transfer of energy; amount of work depends on how heavy and/or vigorous |
| Potential | Chemical make up |
| Chemical | Form of potential; energy stored in bonds of molecules |
| Kinetic | Moving object |
| Gravitational Potential | Due to gravity |
| Thermal | Heat through motion |
| Radiant | Energy of electromagnetic radiation |
| 1st Law of Thermodynamics | Concerned with the conservation of energy: When one form of energy is transformed to other forms, the total amount of energy in a system and its surroundings is the same. |
| 2nd Law of Thermodynamics | The quality of the energy declines with each energy transfer of transformation; also states that entropy increases |
| Entropy | The amount of disorder in a system |
| Food Web | A set of feeding relationships among organisms indicating the flow of energy and materials in an ecosystem. |
| Trophic Level | Identifies species position in the overall movement of materials or energy through an ecosystem. |
| Carnivores | Feeds on other living; predators, or secondary consumers |
| Omnivores | Feeds on plants/animals |
| Herbivores | Plants; primary consumers |
| Primary Producers | Usually plants/algae (autograph) Means of photosynthesis |
| Detrivoes | Feed on organic matter; decomposers |
| Gross Primary Production | Total amount of organic matter produced by primary producers in an ecosystem over a period of time. |
| New Primary Production | Amount of food energy available for other organisms that feed on primary producers. |
| Secondary (consumer) Production | Amount of consumer biomass or energy that goes into growth or reproduction. |
| Conservation of Matter | Matter is neither created nor destroyed. |
| Biochemical Cycle | Cyclic path of an inorganic substance through the Earth system |
| Carbon Cycle | Key processes: photosynthesis, reparation |
| Substance Economy | Individuals or groups produce of harvest enough resources from the natural environment to largely support themselves. |
| Market Economy | Production and consumption of goods and services made by the people. |
| Centrally Planned Economy | Central authority makes decisions. |
| State | Property owned, by federal, state, or local governments. |
| Private | Property owned by individuals. |
| Open Access | Property in which there are no restrictions about who may enter and exploit its resources; first come, first served. |
| Common | Property owned or controlled by a community, such as indigenous tribe. |
| Positive Feedback | Increase in some factors produces increases within the system. |
| Economic Externality | Cost or benefit to environment/society resulting in production and use of product that is not included in market price. |
| Market Failure | Society is harmed because inefficiency in how goods and services are distributed. |
| Common Pool Resource | Owned and utilized in common by a community. |
| Common and Control Regulations | Regulation of an industry/activity, indicating what is and is not allowed and penalties |
| Environmentaleconomics | Assessment and management of costs and benefits of economic impacts on the environment |
| Natural Capital | Value of Earth's natural assets (minerals, air, water) |
| Ecological Economics | Attempt to build a bridge between humans, institutions, rest of nature |
| Ecosystem Services | Benefits humans receive from natural ecosystems (food, water purification) |
| Market Based Approach | Alternative to command and control regulation that seeks to encourage adherence to social or environmental goals using principles of supply and demand. |
