| 8398290820 | Food web | Expanded, more complete version of a food chain that shows all of the major plants in the ecosystem, the various animals that eat them, and the animals that eat other animals. |  | 35 |
| 8398290823 | Biomagnification | Biomagnification, also known as bioamplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain. |  | 36 |
| 8398290824 | Homeostasis | The tendency of the body to seek and maintain a condition of balance or equilibrium within its internal environment, even when faced with external changes. A simple example of homeostasis is the body's ability to maintain an internal temperature around 98.6 degrees Fahrenheit, whatever the temperature outside. |  | 37 |
| 8398290827 | Evaporation | the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. |  | 38 |
| 8398290828 | Transpiration | the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. |  | 39 |
| 8398290829 | Condensation | the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets. |  | 40 |
| 8398290830 | Nitrogen Fixation | a process in which nitrogen (N2) in the atmosphere is converted into ammonia (NH3). Atmospheric nitrogen or molecular dinitrogen (N2) is relatively inert: it does not easily react with other chemicals to form new compounds. |  | 41 |
| 8398290831 | Denitrification | a microbially facilitated process of nitrate reduction that may ultimately produce molecular nitrogen (N2) through a series of gaseous nitrogen oxide products. |  | 42 |
| 8398290832 | Limiting Factor | things that prevent a population from growing any larger. For example, 10 rabbits may live in a habitat that has enough water, cover and space to support 20 rabbits, but if there is only enough food for ten rabbits, the population will not grow any larger. | | 43 |
| 8398290833 | Biomass | things that prevent a population from growing any larger. For example, 10 rabbits may live in a habitat that has enough water, cover and space to support 20 rabbits, but if there is only enough food for ten rabbits, the population will not grow any larger. |  | 44 |
| 8398290834 | Keystone Species | a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically (Ex: Otter) |  | 45 |
| 8398290835 | Biomass Energy Pyramid | a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem. Biomass is the amount of living or organic matter present in an organism. |  | 46 |
| 8398290836 | 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. |  | 47 |
