1 Section 4.2 Terrestrial and Aquatic Biomes Chapter 4Section 4.2Terrestrial and Aquatic Biomes
2 BiomesBiome – is a large geographical region with a specific range of temperatures and precipitation, and the organisms are adapted to those conditions of temperature and precipitation.There are two major types of biomes:TerrestrialAquatic
4 Terrestrial Biomes in Canada There are 4 terrestrial biomes in Canada:TundraTaigaTemperate Deciduous ForestGrasslands
5 Terrestrial Biomes in Alberta There are 3 terrestrial biomes in Alberta:TaigaGrasslandsTemperate deciduous forest
6 Taiga (Boreal Forest) Biome Found in Northern Alberta and along the Rocky Mountains.Abiotic factors:Changeable weatherSoil contains some water and is acidicAverage precipitation
7 Biotic factors :- black and grizzly bears- wolverines- weasels- moose- deer- grouse- owls- spruce and pine (coniferous or cone-bearing)- shrubs, ferns, mosses and lichens
8 There are different ecosystems within the taiga depending on the amount of sunlight. One of these ecosystems is in the muskeg.Muskegs:- muskeg is the thin layer of soil above the permafrost that is swampy and boggy- in the summer when snow melts, the permafrost prevents the water from moving all the way to the water table, so it remains in the top layers, saturating them- muskegs are home to moss, lichens, small shrubs and tall grasses
18 Aquatic Biomes in Alberta There is 1 aquatic biome in Alberta:1. Fresh water or lake ecosystem
19 Fresh Water BiomesThe fresh water biomes in Alberta are made up of lake ecosystems.Lake ecosystems have 3 main zones:Littoral zoneLimnetic zoneProfundal zone
20 Littoral ZonesThe area from the shore of the lake or pond to the point where no more plants grow in the lake bottom.It is warm, shallow and has lots of oxygen.It has many photosynthetic organisms and is the most productive zone.
22 Limnetic ZonesThe area of a lake or pond in which there is open water and sufficient light for photosynthesis to occur.There are a few photosynthetic organism.Contains consumers such as fish, tadpoles, and birds.
23 Profundal ZonesThe region of a lake beneath the limnetic zone, in which there is insufficient light for photosynthesis to occur.It has cool temperatures and is very dark.There are few nutrients, low oxygen due tono photosynthesis and a high number of bacteria.It contains low oxygen organisms such as carp.
