| Species | a species is one of the basic units of biological classification and a taxonomic rank. |
| Population | is all the organisms that both belong to the same species and live in the same geographical area. |
| Community | a group of interacting people, possibly living in close proximity, and often refers to a group that shares some common values, and is attributed with social cohesion within a shared geographical location, generally in social units larger than a household |
| Ecosystem | consists of the economic system of a country or other area; the labor, capital and land resources; and the manufacturing, trade, distribution, and consumption of goods and services of that area |

| Heterotroph | organism that abtains energy from the food it consumes |
| Food web | is a linear sequence of links in a food web starting from a trophic species that eats no other species in the web and ends at a trophic species that is eaten by no other species in the web |
| Trophic level | of an organism is the position it occupies in a food chain |
| Biomass | as a renewable energy source, is biological material from living, or recently living organisms |
| 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 | is a factor that controls a process, such as organism growth or species population, size, or distribution. |
| Weather | is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy |
| Climate | encompasses the statistics of temperature, humidity, atmospheric pressure, wind, rainfall, atmospheric particle count and other meteorological elemental measurements in a given region over long periods. |

| Biotic Factor | is any living component that affects another organism, including animals that consume the organism in question, and the living food that the organism consumes.each biotic factor needs energy to do work and food for proper growth |
| Abiotic factor | non-living chemical or physical factor in the environment, such as soil, pH, forest fire, etc |

| carrying capacity | a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment |
| Demography | is the statistical study of human population. |
| demographic transition | is the transition from high birth and death rates to low birth and death rates as a country develops from a pre-industrial to an industrialized economic system. |
| green revolution | refers to a series of research, development, and technology transfer initiatives, occurring between the 1940s and the late 1970s, that increased agriculture production around the world, beginning most markedly in the late 1960s. |
| renewable resourse | if it is replaced by natural processes and if replenished with the passage of time. |
