| Term | Definition |
|---|---|
| environment | the physical, chemical and the biotic factors that play a role on all organisms and ecosystem and determine its form and survival |
| environmental science | the studies behind the earth’s physical chemical biological and geological processes to understand how how issues like pollution control migration , and the effects of global warming and chemical change, changes,affects the earth |
| ecosystem | a biological community of interacting organisms and environment |
| biotic | resulting from living things and their ecological relationships |
| abiotic | physical not biological not derived from the living organisms |
| environmentalist | a person who is concerned with and fights for the protection of the environment |
| ecosystem service | the many benefits to humans provided by the environment and ecosystems |
| economic service | types of provisioning services like drinking water, timber, wood fuel, natural gas, oils, plants that can be made into clothes and other materials, and medicinal benefits |
| 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 living organisms consisting of similar individuals capable of exchanging genes or interbreeding |
| 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 |
| anthropogenic | environmental change caused or influenced by people, either directly or indirectly. |
| sustainability | the ability to be maintained at a certain rate or level. |
| biophilia | a hypothetical human tendency to interact or be closely associated with other forms of life in nature |
| 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 | the group of subject that receive no treatment or a standardized treatment. |
| sample size | determination is the act of choosing the number of observations or replicates to include in a statistical sample. |
| replication (during experimentation) | repetition of an experiment or observation in the same or similar conditions |
| theory | a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method |
| 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 | lary effect or motion, is when liquid flows through narrow spaces without external forces, such as gravity |
| 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 | have as the foundation for (something); use as a point from which (something) can develop. |
| ph | a measure of how acidic/basic water is |
| 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 | the amount of matter stays the same, even when matter changes form. |
| 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 |
| 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 | genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on |
| renewable energy | energy that comes from a source that won't run out |
| nonrenewable energy | sources that will run out or will not be replenished in our lifetimes |
| chemical energy | energy stored in the bonds of atoms and molecules. |
| first law of thermodynamics | the total energy of a system remains constant, even if it is converted from one form to another |
| second law of thermodynamics | an isolated system's entropy will never decrease over time. |
