Cycles & Competition
Cycles of Matter & Organisms Interactions
| Term | Definition |
|---|---|
| Law of Conservation of Energy | States energy can neither be created or destroyed - only converted from one form of energy to another. |
| Law of Conservation of Matter | States matter is neither created nor destoryed during a chemical or physical changes. |
| evaporation | Process in which liquid water changs to water vapor (gas) due to increase temperature/heat. |
| condensation | Process that forms clouds in which water vapor (gas) changes to liquid water due to decrease temperature/heat. |
| transpiration | Process in plants that releases water from its leaves. |
| precipitation | The process in which water falls from clouds in the form of rain, snow, sleet, or hail. |
| nitrogen "free nitrogen" | Gas that makes up 78% of the Earth's atomosphere, not in a usable form for living organisms, and is not combined with other elements. |
| nitrogen fixation | The process of converting free nitrogen into a usable form called nitrogen compound. |
| nitrogen compound | Organic compounds needed by all living things to build proteins and other important body chemicals. |
| nitrogen cycle | The process of nitrogen cycling through the ecosystem and living things. |
| water Cycle | The process of water cycling through the ecosystem and living things. |
| carbon cycle | The process of carbon cycling through the ecosystem and living things. |
| oxygen cycle | The process of oxygen cycling through the ecosystem and living things. |
| photosynthesis | The process in which producers/autotrophs capture and use sunlight to make its own food. |
| cellular respiration | The process in which all organisms convert food/glucose to energy. |
| decomposition | Organisms that break down biotic waste and dead organism and return raw materials and nutrients back to the soil, water, & air. |
| producer | Organisms that make their own food by the process of photosynthesis. |
| consumer | Organisms that obtain their food and energy by eating producers and other consumers. |
| dew | The process of water vapor changing to water directly on a cool surface. |
| niche | The role of an organism in its habitat and includes how an organism obtains its food. |
| adaptations | The behaviors and physical characteristics that allow organisms to live successfully in their environment. |
| competition | The struggle between organisms to survive as they use the same limited resources. |
| predation | Interaction in which one organism kills another for food or nutrients. |
| symbiosis | Relationship in which two species live closely together. |
| commensalim | Type of symbiosis in which one species benefits and the other species is neither helped nor harmed. |
| mutualism | Type of symbiosis in which both species benefit/helped. |
| parasitism | Type of symbiosis in which one organism lives with, on, or inside another organism, harming it. |
| habitat | An environment that provides the things a specific organism needs to lives, grow, and reproduce. |
| host | An organism that harbors another organism, inside or near their body, in a symbiotic relationship. |
| parasite | An organsim that lives on or in, feeds, and harms another organism. |
