- 1Aphotic zoneIs the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1 percent of sunlight penetrates.
- 2BiodiversityBiodiversity is the shortened form of two words "biological" and "diversity". It refers to all the variety of life that can be found on Earth (plants, animals, fungi and micro-organisms) as well as to the communities that they form and the habitats in which they live.
- 3BiomeA large naturally occurring community of flora and fauna occupying a major habitat, e.g. forest or tundra.
- 4ChaparralA dense impenetrable thicket of shrubs or dwarf trees
- 5ChemosynthesisInvolves the use of energy released by inorganic chemical reactions to produce food.
- 6ClimateThe average weather in a given area over a longer period of time.
- 7Coral reefA ridge of rock in the sea formed by the growth and deposit of coral.
- 8DesertAreas that receive very little precipitation
- 9DesertificationLand degradation in typically dry areas resulting from various factors, including climatic variations and human activities.
- 10EstuaryIs an area where a freshwater river or stream meets the ocean.
- 11Eutrophic lakeDescribing a situation where of a water body has lost so much of its dissolved oxygen that normal aquatic life begins to die off.
- 12GrasslandA large open area of country covered with grass, especially one used for grazing.
- 13GyreA circular or spiral motion or form; especially : a giant circular oceanic surface current.
- 14Hydrothermal vent communityOccur at both diverging and converging plate boundaries.
- 15Kelp forestAre large brown algae that live in cool, relatively shallow waters close to the shore.
- 16Intertidal zoneIs the area that is exposed to the air at low tide and underwater at high tide (the area between the low and high tide lines). This area can include many different types of habitats, including steep rocky cliffs, sandy beaches, or wetlands
- 17Limnetic zoneThe open water area where light does not generally penetrate all the way to the bottom.
- 18Littoral zoneThe littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore.
- 19Nearshore zoneThe shoreline area that encompasses the foreshore
- 20Northern coniferous forestThe northern coniferous forest biome occupies a vast area below the tundra, extending completely across Canada and into interior Alaska. The biome is also referred to as the boreal forest or taiga. Compared to the arctic tundra, the climate of the boreal forest is characterized by a longer and warmer growing season.
- 21Oligothrophic lakeThose that are unproductive: net primary production is only between 50 and 100 milligrams of carbon per square metre per day, nutrients are in poor supply, and secondary production is depressed.
- 22Open oceanIs the area of the ocean outside of coastal areas. The open ocean lies over the continental shelf
- 23Ozone holeA region of marked thinning of the ozone layer in high latitudes, chiefly in winter, attributed to the chemical action of chlorofluorcarbons and other atmospheric pollutants. The resulting increase in ultraviolet light at ground level gives rise to an increased risk of skin cancer.
- 24Ozone layerA thin part of the Earth's atmosphere that absorbs almost all of the sun's harmful ultraviolet light
- 25Permafrostpermanently frozen layer below Earth's surface. It consists of soil, gravel, and sand, usually bound together by ice.
- 26Photic zoneRelating to, or involving light especially in relation to organisms.
- 27PhytoplanktonIn a balanced ecosystem, they provide food for a wide range of sea creatures. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow
- 28PlanktonPlankton are marine drifters — organisms carried along by tides and currents. ... Plankton are usually microscopic, often less than one inch in length, but they also include larger species like some crustaceans and jellyfish.
- 29Profundal zoneThe bottom and deepwater area of freshwater ecosystems that lies beyond the depth of effective light penetration (see compensation level). In shallow freshwater systems, such as ponds, this zone may be missing.
- 30Rain shadowA rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather.
- 31SavannaA treeless plain especially in Florida. 2a : a tropical or subtropical grassland (as of eastern Africa or northern South America) containing scattered trees and drought-resistant undergrowth.
- 32Temperate deciduous forestIs a biome that is always changing. It has four distinct seasons: winter, spring, summer and fall. Winters are cold and summers are warm. Temperate deciduous forests get between 30 and 60 inches of precipitation a year.
- 33ForestA large area covered chiefly with trees and undergrowth.
- 34Temperate rain forestTemperate broad-leaved forests, sometimes called temperate rainforests, are dominated by evergreen vegetation. These forests grow in regions where year-round rainfall is high and steady and frost is rare.
- 35Tropical scrub forestThe tropical scrub forest is a biome that makes up the arid land. This type of biome consists of desert region and areas of low-lying regions, there are dense bushes which are growing over these places
- 36TundraTundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool.
- 37UpwellingUpwelling is a process in which deep, cold water rises toward the surface
- 38WetlandsWetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season.
- 39PlanktonSmall (often microscopic) plants and animals floating, drifting or weakly swimming in bodies of fresh or salt water.
