Ecology - Cycles
| Question | Answer |
|---|---|
| The evaporation of water from the leaves of plants. | transpiration |
| Water falling from the sky in the form of rain, snow, or ice. | precipitation |
| Liquid water changing into a gas - usually under the influence of heat. | evaporation |
| The conversion of water vapor into a liquid. | condensation |
| The movement of water into the ground through pores in the soil. | seepage (percolation) |
| Water that flows on the surface until it collects in a body of water. | run-off |
| The collection of water from the soil from the roots of plants. | root uptake (absorption) |
| Liquid water precipitation. | rain |
| Precipitation in the form of flakes or crystalline water. | snow |
| Rain or melted snow that freezes before it hits the ground; falls as a solid. | sleet |
| Liquid water precipitation that falls when surface temps. are below freezing, sometimes freezing upon contact with a surface. | freezing rain |
| Ice that forms in thunderclouds high in the cool atmosphere and falls to the ground. | hail |
| The process of converting nitrogen gas into a form of nitrogen plants can use. | nitrogen fixation |
| The process of making nitrogen gas from nitrogen compounds in the ground. | denitrification |
| Type of organisms that perform nitrogen fixation and denitrification. | bacteria |
| A type of nitrogen fixation that involves lightning. | atmospheric fixation |
| A type of nitrogen fixation that involves industries making fertilizers. | industrial fixation |
| A type of nitrogen fixation that requires bacteria. | biological fixation |
| Process that removes carbon from the atmosphere. | photosynthesis |
| Processes that can return carbon to the atmosphere. | cellular respiration, volcanic activity, burning of fossil fuels, organism decay, uplift and erosion. |
| The exchange and transfer of molecules amongst organisms and between organisms and the earth. | biogeochemical cycles |
| Soil bacteria converting ammonium in to nitrites and nitrates, making nitrogen available for plants. | nitrification |
| Decomposers like bacteria or fungi converting nitrogen gas OR nitrogen compounds in the soil into ammonium. | ammonification |
| Living organisms taking up nitrogen compounds and incorporating them into their tissues. | assimilation |
