| Term | Definition |
|---|---|
| Environment | the natural world, as a whole or in a particular geographical area, especially as affected by human activity. |
| environmental science | the study of the interactions between the Earth's natural environment and humans, and how to protect and improve the environment. |
| ecosystem | a biological community of interacting organisms and their physical environment. |
| biotic | relating to or resulting from living things, especially in their ecological relations. |
| Abiotic | physical rather than biological; not derived from living organisms. (not alive) |
| environmentalist | a person who is concerned with or advocates the protection of the environment. |
| ecosystem service | the benefits that humans get from healthy ecosystems, which are also known as natural capital. |
| economic service | an intangible act or use that a customer pays for. |
| Biodiversity | the variety of life in the world or in a particular habitat or ecosystem. |
| genetic diversity | the range of different inherited traits within a species. |
| species | a group of organisms that can reproduce with each other in nature and produce fertile offspring. |
| species diversity | the number of different species in a particular area and their relative abundance. |
| speciation | the formation of new and distinct species in the course of evolution. |
| greenhouse gases | a gas that contributes to the greenhouse effect by absorbing infrared radiation, e.g., carbon dioxide and chlorofluorocarbons. |
| anthropogenic | of, relating to, or resulting from the influence of human beings on nature. |
| sustainability | The ability to be maintained at a certain rate or level |
| biophilia | the idea that humans have an innate tendency to connect with nature and other life forms |
| ecological footprint | the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources. |
| hypothesis | a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. |
| control group | a group in an experiment that doesn't experience the variable being tested and serves as a benchmark for comparing the results of other groups. |
| sample size | the number of observations or individuals included in a study or experiment. |
| replication | the action of copying or reproducing something. |
| theory | a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained. |
| surface tension | the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area. |
| capillary action | the process of a liquid flowing in a narrow space in opposition to or at least without the assistance of any external forces |
| Acid | a chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically, a corrosive or sour-tasting liquid of this kind. |
| Base | a substance that can neutralize acids by reacting with hydrogen ions |
| pH | potential of hydrogen, since pH is effectively a measure of the concentration of hydrogen ions (that is, protons) in a substance. |
| chemical reaction | a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. |
| law of conservation of matter | matter is neither created nor destroyed, |
| carbohydrate | any of a large group of organic compounds that includes sugars, starch, and cellulose, containing hydrogen and oxygen in the same ratio as water (2:1) and used as structural materials and for energy storage within living tissues. |
| protein | any of a class of nitrogenous organic compounds that have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., |
| lipid | any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids. |
| Nucleic Acid | a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain. |
| DNA/RNA | nucleic acids that carry genetic information essential for life. |
| renewable energy | energy from a source that is not depleted when used, such as wind or solar power. |
| nonrenewable energy | a natural resource that is finite and will eventually run out because it is used up faster than it can be replenished |
| chemical energy | energy stored in bonds of chemical compounds |
| first law of thermodynamics | energy can neither be created nor destroyed, only altered in form. |
| second law of thermodynamics | the state of entropy of the entire universe, as an isolated system, will always increase over time |
