Ecology
| Question | Answer |
|---|---|
| Stable ecosystem | The ability of an ecosystem to maintain its structure and function over long periods of time and despite despite disturbances |
| Predation | the preying of one animal on others. |
| Primary producers | are the organisms in an ecosystem that produce biomass from inorganic compounds. |
| Food chain | . a hierarchical series of organisms each dependent on the next as a source of food. |
| Primary Consumers | An animal that feeds on plants, a herbivore |
| Trophic Level | 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 |
| Autotrophs | Is an organism that produces complex organic compounds from simple substances |
| heterotrophs | An organism deriving its nutritional requirements from complex organic substances |
| Herbivores | an animal that feeds on plants. |
| Carnivores | Organism that obtains energy by eating animals |
| omnivores | An animal or person that eats food of both plant and animal orgin |
| Number Pyramid | A graphical representation in the form of a pyramid showing the feeding relationship and the number of organisms at each trophic level. |
| Food web | a system of interlocking and interdependent food chains. |
| Ecological pyramid | An ecological pyramid (also trophic pyramid or energy pyramid) is a graphical representation designed to show the biomass or biomass productivity at each trophic level in a given ecosystem. |
| Energy Pyramid | An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain. |
| Detritivore | an animal that feeds on dead organic material, especially plant detritus. |
| Limiting factors | “is a factor that controls the growth of a population” |
| Biomass pyramid | is the amount of living or organic matter present in an organism. |
| Field of Geology | the science dealing with the chemical changes in and the composition of the earth's crust. |
| Carbon Cycle | Biochemical cycle in which Carbon is exchanged among the biosphere |
| Abiotic | The factors in an ecosystem that are not organic in nature, for example: weather, minerals, terrain, etc. |
| Ecological succession | is the observed process of change in the species structure of an ecological community over time. |
| Biotic | Of, relating to, or resulting from living things, especially in their ecological relations |
| Primary succession | One of the two types of biological And ecological succession of plant life, occurring in an environment in which new substances devoid of vegetation and usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited |
| Pioneer species | are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem. |
| Climax community | is a historic term that expressed a biological community of plants and animals and fungi which, through the process of ecological succession |
| Secondary succession | is the succession that occurs after the initial succession has been disrupted and some plants and animals still exist. |
| Nitrogen cycle | is the process by which nitrogen is converted between its various chemical forms. |
| Elemental nitrogen | One of the four most abundant elements on the planet. |
| Deposition | the action of deposing someone, especially a monarch. |
| Atmosphere | the envelope of gases surrounding the earth or another planet. |
| Nitrogen fixation | is a process by which nitrogen (N2) in the atmosphere is converted into ammonium (NH4). |
| Denitrifying Bacteria | their primary purpose being to metabolise nitrogenous compounds, with the assistance of the nitrate reductase enzyme, to turn oxides back to nitrogen gas or nitrous oxides for energy generation. |
| Hydrologic/water cycle | describes the continuous movement of water on, above and below the surface of the Earth. |
| Ozone layer | refers to a region of Earth's stratosphere that absorbs most of the Sun's UV radiation. |
| Greenhouse effect | is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all |
| Geosphere | any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere. |
| Sustainability | is how biological systems endure and remain diverse and productive. Long-lived and healthy wetlands and forests are examples of ... |
| Soil Erosion | was a big problem in the Midwestern United States in the 1930s dust bowl. |
| Carrying capacity | the number or quantity of people or things that can be conveyed or held by a vehicle or supported by the ecosystem. |
| Recycling Nutrients | the movement and exchange of organic and inorganic matter back into the production of living matter. The process is regulated by food web pathways that decompose matter into mineral nutrients. |
| agricultural technology | Agricultural machinery is machinery used in the operation of an agricultural area or farm. |
| Industrial Technology | the use of engineering and manufacturing technology to make production faster, simpler and more efficient. |
| Renewable resource | is a natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring ... |
| alternative energy technology | Wind power, solar power, methane |
| Limiting factors | Things that prevent a population from growing any larger |
| competition | the act of two organisms fighting for the same resource. |
| Symbiotic relationship | are obligate, meaning that both symbionts entirely depend on each other for survival. For example, many lichens consist of fungal ... |
| Population density | Number of individual per unit area |
| Population | Group of individuals from the same species that live in the same area |
| CHON | the four most abundant elements on the planet. |
| Nonrenewable Resources | A resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. |
| Density dependent | processes occur when population growth rates are regulated by the density of a population. |
| Parasitism | is a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host. |
| density independent | exert their influences on population size regardless of the population's density. |
| Mutualism | Is the way two organisms of different species exist in a relationship in which each individual benefits. |
| Commensalism | is a class of relationship between two organisms where one organism benefits without affecting the other. |
| parasitism | is a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host. |
| population | A group of organisms of one species that interbreed and live in the same place at the same time |
