| Question | Answer |
|---|---|
| The amazing person that made this StudyStack | Ashley B-Modified by Mr. W |
| Ecology | The scientific study of interactions among organisms and their environment |
| species | a group of similar organisms that can breed and produce fertile offspring |
| population | a group of individuals that belong to the same species and live in the same area |
| community | all the interacting living components of an ecosystem, think food web, symbiotic relationships, competition, etc |
| habitat | place where the species live |
| ecosystem | all the organisms that live in an area with their physical environments |
| biome | a group of ecosystems that share a similar climate and have a typical types of biodiviersity |
| biotic factors | anything living in an environment |
| abiotic factors | any nonliving part in an ecosystem |
| environment | all conditions or factors surrounding an organism |
| observation | first step to ask about technology |
| experimentation | used to test hypothesis |
| models | pictures, diagrams, computer programs, etc that are used to help explain a concept and can be used to make predictions |
| Autotroph/primary producers | use the sun to make there own food |
| chemoautotrophs | chemical energy is used to produce carbohydrates |
| photosynthesis | captures light energy and uses it to power chemical reactions to turn carbon dioxide and water into sugar and oxygen |
| heterotrophs | rely on other organisms for their energy |
| consumer | those eat other organisms |
| herbivores | eats plants |
| omnivores | eats both plants and animals |
| carnivores | eats animals |
| detritivores | feed on detritus often obtaining extra nutrients from the bacteria,algae, and other microorganisms that grow on and around it |
| decomposers | feed by chemically breaking down organic matter |
| scavengers | animals that consume the carcasses of other animals that have been killed by predators or have died of other causes |
| food chain | a series of steps in which organisms transfer energy by eating and getting eaten |
| foodweb | network of complex interactions formed by the feeding relationship among various organisms in an ecosystem |
| phytoplankton | floating algae |
| zooplankton | diverse group of small swimming animals |
| trophic level | each step of the food web or food web |
| ecological pyramids | show the amount of energy or matter contained within each trophic level |
| energy pyramid | a model that shows the distribution of energy in an ecosystem. |
| 10% rule | the process in which 10% of the energy in each trophic level gets passed on to the next |
| trophic cascade | is when one disruption to the food web causes a chain of events to happen |
| biogeochemical cycles | closed loops that elements pass from one organism to the next through |
| water cycle | the process of how water moves |
| condensation | the conversion of a vapor or gas to a liquid |
| precipitation | rain, snow, sleet, or hail that falls to the ground |
| transpiration | process where plants absorb water through the roots and then give off water vapor through pores in their leaves |
| evaporation | process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure |
| respiration | breathing |
| nutrients | a substances that are essential for growth and maintenance of life |
| carbon/oxygen cycle | process of carbon dioxide/oxygen changing forms as it is used in the ecosystem |
| equation of life | 6H20 + 6CO2 <--->C6H12O6 + 6O2 |
| nitrogen cycle | the process of Nitrogen changing form and being conserved as it is used in the ecosystem |
| nitrogen fixation/ammonification | turning gaseous nitrogen into a form that can be used by bacteria and other life forms |
| denitrification | the process of bacteria converting nitrogen gas into ammonia |
| assimilation | turning inorganic nitrogen into organic forms(nucleic acids and proteins) |
| bacteria | are microorganisms important for the nitrogen cycle and decomposition |
| phosphorus cycle | the process of rocks and sediments wearing down and releasing phosphorus |
| dissolved phosphorus | ionic phosphorus dissolved in the water. |
| limiting nutrients | any nutrient that a lack there of will prevent growth or life |
| stream chemistry | all the different chemical properties that affect the quality of the aquatic environment. |
| parameters | the acceptable range of different properties of the stream |
| pH | a figure expressing the acidity or alkalinity of a solution on a logarithmic scale |
| buffer | a solution that resists changes in pH when acid or alkali is added to it |
| DO | the amount of gaseous oxygen (O2) dissolved in the water |
| dead zones | a place with no life as a result of a lack of O2 |
| hypoxia | a deficiency in O2 |
| pollution | the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects. |
| fertilizers | a chemical or natural substance added to soil or land to increase its fertility |
| nutrient loading | increasing the level of nutrients to the environment at a level faster than they can be consumed in a healthy ecosystem |
| discharge | the amount of water that passes a point during a certain period of time. |
| eutrophication | excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen |
| concentration | the measure of the amount of a solute(nutrient or pollutant) in a solution |
| nitrification | process of turning ammonia or ammonium to nitrates |
| biospere | the earth |
