Aquatic Ecosystem
Science Vocabulary
| Question | Answer |
|---|---|
| aquatic life zones | aquatic equivalents of biomes |
| salinity | amounts of various salts |
| marine | estuaries, coastlines, coral reefs, coastal marshes, mangrove swamps, oceans |
| freshwater | lakes, ponds, streams, rivers, inland wetlands |
| plankton | 1 group of weakly swimming, free-floating carried by currents |
| phytoplankton | plant plankton |
| zooplankton | animal plankton |
| nekton | 2nd group of organisms strongly swimming consumers (fish, turtles, whales) |
| benthos | 3rd group dwells on bottom (barnacles, oysters) |
| decomposers | 4th group that break down organic compounds in dead bodies and wastes of aquatic organisms |
| euphotic zone | upper layer through which sunlight can penetrate |
| coastal zone | warm, nutrient-rich, shallow water that extends from the high-tide mark on land to gently sloping, shallow edge of continental shelf |
| continental shelf | submerged par of the continents |
| estuary | partially enclosed area of coastal water where salt water mixes with freshwater and nutrients from rivers, streams, and runoffs from land |
| coastal wetlands | land covered with water all/part of the year |
| intertidal zone | area of shore line between low and high tides |
| barrier islands | low, narrow, sandy islands that form offshore from a coastline |
| open sea | sharp increasing in water depth at the edge of the continental edge separates the coastal zone from vast volume of ocean |
| bathyal zone | dimly lit middle zone that doesn't contain photosynthesizing producers because lack of sunlight |
| abyssal zone | lowest zone, dark and very cold and has little dissolved oxygen |
| lakes | large natural bodies of standing freshwater formed when precipitation, runoff, or ground water seepage filled depressions in earth's surface |
| littoral zone | shallow sunlight waters near shore to depth at which rooted plants stop growing and has high biological diversity |
| limnetic zone | open sunlit water surface layer away from shore that extends to depth penetrated by sunlight |
| profundal zone | deep, open water where it's too dark for photosynthesis |
| benthic zone | bottom of lake, mostly decomposes and detritus feeders and fish that swim 1 zone to other inhabit it |
