A biome is a region with similar biotic and abiotic components. Biotic = living things Abiotic = non-living things (air, water, soil, etc.) If biotic and abiotic conditions are the same, similar biomes can exist far apart. Ex- BC same as New Zealand Examples of Biomes: Boreal forest, desert, grassland, permanent ice, temperate deciduous forest, temperate rainforest, tropical rainforest, and tundra. Biotic

Living vs organisms Plants Animals Fungi Bacteria Abiotic Non

living Sunlight Soil Moisture Temperature Factors that Influence the Characteristics and Distribution of Biomes Certain characteristics help to identify biomes.

Temperature and precipitation are two of the most important abiotic factors. Other factors include latitude, elevation, and ocean currents. (c) McGraw Hill Ryerson 2007 Biomes of the World See pages 10 - Biomes Worksheet Influencing Factors Temperature Precipitation (rainfall, snow, mist & fog)

Latitude Elevation Ocean Currents Influencing factors Latitude is an abiotic factor that influences biomes. Latitude is the distance north and south from the equator. Latitude influences both temperature and precipitation. The

tropical zone has very warm temperatures and high precipitation. The tropical zone receives more direct sunlight than do temperate zones. Elevation also influences biomes. The atmosphere is thinner at higher elevations, and therefore less heat is retained. Windward sides of mountains are wet, leeward sides are very dry.

Ocean currents carry warmth and moisture to coastal areas. Where warm currents meet land, temperate biomes are found. How to read a graph Practice Problems pg. 13 Identify

the biome 1. the region has an average annual precipitation of about 175 cm and an average annual temperature of 5 degrees Celsius. 2. the region ranges in temperature between 0 and 20 degrees and receives about 100 cm of rain 3. The region has low average annual precipitation and an average annual temperature that ranges between -18 and -8 degrees. 4. The region has high average annual precipitation and an average annual temperature. Practice Problem Answers 1. Boreal forest

2. Temperate deciduous forest 3. Tundra 4. Temperate rainforest Climatographs Climate refers to the average pattern of weather conditions of a large region over a period of 30 years or more. A climatograph shows the average temperature and precipitation for a location over a period of 30 years or more. Examine the differences between the

climatographs for Tofino and Osoyoos (c) McGraw Hill Ryerson 2007 Lab 1-1C Get into partners Start to work on parts 1-3 Grab a piece of graph paper For a climatograph. Adaptations and Biomes Biomes are often identified with characteristic biotic factors,

such as a cactus in the desert or a caribou on the tundra. Many of these characteristic factors have special adaptations for that biome. An adaptation is a characteristic that allows an organism to better survive and reproduce. 1. Structural adaptation a physical feature that helps an organism survive 2. Physiological adaptation a physical or chemical event inside the body of an organism that allows it to survive

3. A wolf has large paws to help it run in snow. A wolf maintains a constant body temperature. Behavioural adaptation a behaviour that helps an organism to survive Wolves hunt in packs to capture large prey. (c) McGraw Hill Ryerson 2007 A survey of Biomes Tundra
