| Question | Answer |
|---|---|
| Ecology | The branch of biology that deals with the relations of organisms to one another and to their physical surroundings |
| Biosphere | 1.The regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms |
| Species | 1.A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. ex: dog, cat, humans |
| Population | A community of animals, plants, or humans among whose members interbreeding occurs |
| Community | A set of species found in the same habitat or ecosystem at the same time |
| Ecosystem | A biological community of interacting organisms and their physical environment |
| Autotroph | An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide ex: plants |
| Heterotroph | An organism deriving its nutritional requirements from complex organic substances ex:animals |
| Food Web | A system of interlocking and interdependent food chains ex:plant-> bunny-> fox -> wolf |
| Trophic Level | 1.Each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy |
| Biomass | 1.The total mass of organisms in a given area or volume 2.Organic matter used as a fuel, esp. in a power station for the generation of electricity |
| Biogeochemical Cycle | is a pathway by which a chemical element or molecule moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth |
| Limiting Nutrient | It is the nutrient which is lowest in supply in proportion to demand. (missing nutrient) |
| Weather | The state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc |
| Climate | The weather conditions prevailing in an area in general or over a long period |
| Green House Effect | The trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface |
| Biotic Factor | the action of the organism affects the life of another organism, for example a predator consuming its prey. |
| Abiotic Factor | non-living chemical and physical factors in the environment. |
| Niche | a term describing the relational position of an organism's species |
| Logistic Growth | Change in the size of a population that is rapid at first, then decreases as the population approaches the carrying capacity of its environment. |
| Carrying Capacity | The number of people, other living organisms, or crops that a region can support without environmental degradation |
| Demography | The study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations |
| Demographic Transition | shift in a population from a situation of high natality and high mortality to a new situation where natality and mortality are low. |
| Green Revolution | A large increase in crop production in developing countries achieved by the use of fertilizers, pesticides, and high-yield crop varieties |
| Renewable Resource | any natural resource (as wood or solar energy) that can be replenished naturally with the passage of time |
| Pollutant | waste matter that contaminates the water or air or soil |
| Biodiversity | The variety of life in the world or in a particular habitat or ecosystem. |
| Biological Magnification | is the increase in concentration of a substance |
