| Term | Definition |
|---|---|
| biome | is a group of ecosystem that share similar abiotic and biotic conditions |
| climate | is the average conditions, including temperature and precipitation, over long periods in a given area. |
| weather | day to day conditions in Earth's atmosphere like "sunny and humid" or "cold and snowy" |
| climatographs | a time-based graph that presents a location's average temperature and precipitation |
| Net-primary production | is the organic, or biomass, remains after cellular respiration |
| canopy | the tallest tree form a dense covering |
| emergent layer | the tallest tree pop through the canopy and make up the top layer of the rain forest |
| understory | the underlying layer of vegetation in a forest or wooded area, especially the trees and shrubs growing between the forest canopy and the forest floor |
| Epiphytes | are plants that grow on other plants instead of in soil |
| Deciduous | trees lose their leaves and stop photosynthesis during part of the year |
| estivation | when animals slow their activity for the hot, dry summer months and they enter a cold underground to relax |
| coniferous | woody evergreens that have cones and needles rather than leaves. when you see a pinecone is an example of an coniferous |
| Hibernation | is a deep, sleep like state that an animal enters for most of the winter |
| permafrost | any ground that remains completely frozen — 32°F (0°C) or colder — for at least one or two years straight. |
| Salinity | the concentration of dissolved salt in water, measured in grams per kilogram or parts per thousand (ppt) |
| Photic zone | is a uppermost layer of an aquatic ecosystem, where there is enough sunlight for photosynthesis |
| Aphotic zone | is where there is no sunlight penetrates and photosynthesis cannot occur |
| benthic zone | The very bottom of a body of water |
| Littoral zone | if the water is shallow enough the aquatic plants grow from the mud and reach above the waters surface |
| Limnetic zone | is the farther from the shore, where there are no rooted plants |
| Wetland | are areas of land that are flooded with water at least part of the year. |
| flood plain | areas adjacent to rivers, ponds, lakes, and oceans that are periodically flooded at different points in time |
| Estuaries | are bodies of water partly enclosed by land, that occur where fresh water from land drainage meets the water of an ocean or inland sea |
| Upwelling | the vertical flow of cold, nutrient-rich water toward the surface, occurs where horizontal currents diverge, or flow away from one another |
