| Ecology | study of the interactions between organisms with one anotherand their environment |
| Photosynthesis | Process of plant - converting light energy into chemical energy and sugars using the sun's energy and CO2 in the atmosphere. |
| Ecosystem | self sustaining collection of organisms and their physical environment (includes physical features (abiotic) and living organisms (biotic)) to form a community |
| Habitat | place where an organism lives |
| Niche | an organism's "profession"; what it does for a living (in order to obtain food).. How an organism interacts with its environment |
| Morphology | structure and form of an organism as it relates to function (except vestigial characteristics) |
| Aerobic Respiration | x |
| Abiotic Factors | physical (non-living) environment |
| Biotic factors | Communities of living organisms |
| Ecological Succession | when physical features change, the living community (ecosystem) also undergoes changes. *Process through which an existing community is replaced gradually by another community |
| Climax Community | relatively stable collection of plants and animals that results from ecological succession. Often described by most obvious features: Ex: Redwood Forest Community |
| Biosphere | that part of the earth in which life exists |
| Autotrophs | Self-feeders |
| Heterotrophs | Other-feeders |
| Pyramid of Energy | Total amount of incoming energy at each level |
| Pyramid of Biomes | trophic levels of an ecosystem |
| Nitrogen Fixation | Bacteria in plant roots change free nitrogen into nitrogen compounds |
| Dentrification | When soil breaks down, giving free nitrogen to the atmosphere |
| Carbon Cycle | when carbon is moved through the environment during photosynthesis |
| Population | group of organisms that all belong to the same species and live in a given area |
| NADP | #1 way the energy of sunlight is trapped in chemical bonds |
| NADPH | When NADP accepts a pair of high energy electrons |
| ATP | adenosine triphosphate; produced by green plants; an energy storing compound used by every cell |
