| Term | Definition |
|---|---|
| Law of Conservation of Mass/Matter | Matter can't be created or destroyed, only changed from one form to another. |
| Law of Conservation of Energy | Energy cannot be made or lost but only changed from one form to another. |
| Evaporation | Evaporation is when liquid water turns into vapor and rises into the air. |
| Transpiration | Transpiration is when plants lose water from their leaves into the air. |
| Precipitation | Precipitation is when water falls from the sky as rain, snow, sleet, or hail. |
| Groundwater | Groundwater is water that is found underground in soil and rock. |
| Runoff | Runoff is water that flows over the ground after it rains instead of soaking into the soil. |
| Biotic Factor | Biotic factors are living things in an ecosystem, like plants and animals. |
| Abiotic Factor | Abiotic factors are nonliving things in an ecosystem, like water, air, and rocks. |
| Biosphere | The biosphere is the part of Earth where all living organisms exist. |
| Producer | Producers are organisms, like plants, that make their own food using sunlight. |
| Consumer | Consumers are animals that eat other living things for energy. |
| Condensation | Condensation is when water vapor cools and turns back into liquid water, forming clouds. |
| Water Cycle | The water cycle is the continuous movement of water through evaporation, condensation, and precipitation. |
| Carbon Cycle | The carbon cycle is the process of how carbon moves between the atmosphere, land, and living things. |
| Nitrogen Cycle | The nitrogen cycle is how nitrogen moves between the air, soil, and living organisms in nature. |
| Oxygen Cycle | The oxygen cycle is the process of oxygen moving from the atmosphere into living organisms and back again. |
| Deforestation | Deforestation is when large areas of forests are cut down for land or wood. |
| Cellular Respiration | Cellular respiration is how cells break down sugar and oxygen to make energy. |
| Photosynthesis | Photosynthesis is the process where plants use sunlight to make their own food from carbon dioxide and water. |
| Fossil Fuels | Fossil fuels are natural substances like coal, oil, and gas that are made from ancient plants and animals. |
| Nitrogen Fixation | Nitrogen fixation is when certain bacteria convert nitrogen from the air into a form that plants can use. |
| Ammonification | Ammonification is the process of changing organic matter into ammonia in the soil. |
| Interconnected | Interconnected means that different parts of an ecosystem are linked and depend on each other. |
| Organism | An organism is any living thing, like a plant, animal, or bacteria. |
| Denitrification | Denitrification is when bacteria change nitrates in the soil back into nitrogen gas in the atmosphere. |
