Chapter 4 Section 4.2 Terrestrial and Aquatic Biomes Slide 2 Biomes Biome 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: 1.Terrestrial 2.Aquatic Slide 3 Slide 4 Terrestrial Biomes in Canada There are 4 terrestrial biomes in Canada: 1.Tundra 2.Taiga 3.Temperate Deciduous Forest 4.Grasslands Slide 5 Terrestrial Biomes in Alberta There are 3 terrestrial biomes in Alberta: 1.Taiga 2.Grasslands 3.Temperate deciduous forest Slide 6 Taiga (Boreal Forest) Biome Found in Northern Alberta and along the Rocky Mountains. Abiotic factors: -Changeable weather -Soil contains some water and is acidic -Average precipitation Slide 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 Slide 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 Slide 9 Muskeg Boreal Forest Slide 10 Grassland Biome Found in central and southern Alberta. Abiotic factors: -Fertile soils -Warm temperatures -Rapid decay -Rich humus layers -Less precipitation Slide 11 Biotic factors: -Bison -Deer -Rabbits -Hawks -Yellow-bellied sapsuckers -Grasshoppers -Fescue grasses Slide 12 Grasslands Slide 13 Deciduous Forest Biome Found in central Alberta. Abiotic factors: -Increased sunlight and warmer temperatures -Rich fertile soil -More precipitation Slide 14 Biotic Factors: -Black bears -Weasels -Moose -Deer -Woodpeckers -Deciduous trees (leaves) -Shrubs Slide 15 Deciduous Forest Slide 16 Aquatic Biomes in Canada There are 2 aquatic biomes in Canada: 1.Salt Water 2.Fresh Water Slide 17 Salt Water Fresh Water Slide 18 Aquatic Biomes in Alberta There is 1 aquatic biome in Alberta: 1. Fresh water or lake ecosystem Slide 19 Fresh Water Biomes The fresh water biomes in Alberta are made up of lake ecosystems. Lake ecosystems have 3 main zones: 1.Littoral zone 2.Limnetic zone 3.Profundal zone Slide 20 Littoral Zones The 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. Slide 21 Slide 22 Limnetic Zones The 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. Slide 23 Profundal Zones The 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 to no photosynthesis and a high number of bacteria. It contains low oxygen organisms such as carp.
