Energy in Ecosystems
| Question | Answer |
|---|---|
| Producer | An Organism that uses energy from the sun to make its own food |
| Consumer | Organisms that cannot make their own food and must eat (consume) other organisms to gain energy |
| Decomposer | Organisms that break down dead or decaying plant and animal material in order to get energy |
| Energy Flow | Arrows are used in food chains and food web models to show the direction that energy moves through the chain/web |
| Population | The number of one single type of organism within a given area |
| Food Chain | A path that energy/nutrients follow; a model of the series of feeding relationships among organisms in an ecosystem |
| Food Web | A model that shows how a series of food chains are linked together in an ecosystem |
| Herbivore | Consumers that eat only plants. |
| Carnivore | Consumers that eat only meat. |
| Omnivore | Consumers that eat both plants and meat. |
| Condensation | When a gas changes into a liquid, which happens because of cooling/energy loss |
| Evaporation | When a liquid changes into a gas, which happens because of heating/gaining energy |
| Precipitation | Liquid droplets in the clouds become too heavy and fall to Earth in the form of rain, sleet, snow, or hail |
| Infiltration | Water soaks into the ground, moving downward through cracks and spaces |
| Groundwater | Water that is stored beneath the Earth’s surface |
| Respiration | Breathing- water vapor is released from the lungs of animals when they breathe out |
| Surface Runoff | Water flows over the Earth’s surface and gathers in lakes, streams, and oceans (accumulation) |
| Transpiration | Water evaporates from the leaves of plants |
| Nitrogen Cycle | The continuous circulation of nitrogen from air to soil to organisms and back to air or soil |
| Carbon-Oxygen Cycle | The circulation of oxygen and carbon through Earth’s systems (mainly through photosynthesis (plants) and breathing/respiration (animals) |
| Water Cycle | The continuous movement of water between the Earth’s surface and the air, changing forms among the three states of matter |
| Producers | Organisms that use energy from the sun to make their own food |
| Atmosphere | The layer of gases surrounding Earth |
| Biosphere | All of Earth’s living things |
| Geosphere | The solid and molten rock inside Earth, including soil, rock pieces, and land features on the surface |
| Hydrosphere | All of Earth’s liquid and solid water, including oceans, lakes, rivers, glaciers, and ice caps |
| Ecosystem | A place where living and non-living things interact together |
