BC Biology 10
BC science 10 Biology
| Question | Answer |
|---|---|
| Abiotic | A nonliving organism |
| Adaptation | Characteristics that enable organisms to better survive and reproduce |
| Biome | The largest division of the biosphere, which includes large regions with similar biotic and abiotic components |
| Biotic | Relating to living organisms such as plants, animals, fungi, and bacteria |
| Climate | The average conditions of the atmosphere: precipitation, temperature, and humidity. In a large region over 30 years or more. |
| Climatograph | A graph of climat data for a specLific region; the data ate usually obtained over 30 years from local weather observation stations |
| Commensalism | Symbiotic relationship in which one species benefits and the other species in neither helped or harmed |
| Competition | Harmful interaction between two or more organisms that can occur when organisms compete for the same resource ( such as food ) in the same location at the same time |
| Ecosystems | Is a large region where abiotic and biotic organisms that interact together. |
| Mutualism | A symbiotic relationship in which tooth organisms benefit. |
| Niche | The way in which an individual organism contributes to and fits into its environment. |
| Parasitism | Symbiotic relationship in which one species benefits and the other is harmed |
| Predation | Describ predator prey interactions in which one organism the predator eats all or part of another organism the prey |
| Biodegration | The action of living organisms such as bacteria to break down dead organic matter. |
| Consumers | Something that feeds on something else |
| Decomposers | Organisms that change dead organisms and waste into usable |
| Food Chain | A model that shows the flow of energy from plant to animal and from animal to animal |
| Food Pyramid | A model that shows the loss of energy from one trophic level to another; often called an ecological pyramid |
| Food web | A model of the feeding relationships within an ecosystem; formed from interconnected food chains |
| Producers | Organisms that produce food in the form of carbohydrates during photosynthesis |
| Trophic level | Steps in a food chain that show feeding and niche relationships among organisms |
| Cellular respiration | The process in which both plants and animals release carbon dioxide back into the atmosphere by converting carbohydrates and oxygen into carbon dioxide and water |
| denitrification | The process in which nitrogen is returned to the atmosphere |
| nitrification | The process in which ammonium is converted into nitrate. |
| nutrients | Substances such as the chemicals nitrogen and phosphorus that are required by plants and animals for energy, growth, development, repair, or maintenance; important components of nutrient cycles in the biosphere. |
| photosynthesis | A process in which carbon dioxode enters the leaves of plants and reacts with water in the presence of sunlight to produce carbohydrates and oxygen; photosynthesis also occurs in some micro-organisms. |
| sedimentation | The process in which soil particles and decaying organic matter accumulate in layers on the ground or at the bottom of large bodies of water, contributing to the formation of sedimentary rock. |
| weathering | The process in which rock is broken down into smaller fragments |
| bioaccumulation | The gradual build-up of synthetic and organic chemicals in living organisms. |
| bioremediation | The use of organisms - usually micro-organisms or plants - to break down chemical pollutants in water or soil to reverse or lessen environmental damage. |
| heavy metals | Metalic elements with a high density that are toxic to organisms at low concentrations. |
| keystone species | Species (e.g., Salmon) that can greatly affect population numbers and the health of an ecosystem. |
| parts per million | A measurement of chemical accumulation; 1ppm means one particle mixed with 999 999 other particles |
| PCBs | (polychlorinated biphenyls) synthetic chemicals containing chlorine that are used in the manufacture of plastics and other industrial products, become stored in the tissue of animals, and also persist in the environment. |
| Adaptive radiation | The development of a number of new species from a common ancestor; the new species are adapted to inhabit different niches. |
| climax community | A mature community, such as a boreal forest, tropical rainforest, grassland, or desert, that continues to change over time. |
| ecolgical succession | Changes that take place over time in the types of organisms that live in an area. |
| natural selection | The process in which, over time, the best-adapted members of a species will survive and reproduce. This process makes change in living things possible. |
