Section 1: What is a biome? Section 2: Forest Biomes Section 3: Grassland, Desert, and Tundra Biomes
Chapter 6, Section 1 What is a Biome? Objectives: Describe how plants determine the name of a biome. Explain how temperature and precipitation determine which plants grow in an area. Explain how latitude and altitude affect which plants grow in an area. Key Terms: Biome Climate Latitude Altitude
A biome is a large geographic region characterized by a specific type of climate and certain types of plant and animal communities. Each biome is made up of many individual ecosystems. What is a Biome?
Biome vs. Ecosystem The biosphere is divided into biomes which are divided into smaller ecosystems.
Biomes and Vegetation Ecosystems of the world are grouped into regions called biomes. Biomes are named for the vegetation that grows there. Biomes are described by their vegetation because plants that grow in an area determine the other organisms that can live there.
Biomes and Climate Climate refers to the weather conditions such as temperature, precipitation, humidity, and winds in an area over a long period of time.
Biomes and Climate The climate of a biome is determined by average temperature and precipitation. Most organisms are adapted to live within a particular range of temperatures. Precipitation limits the organisms that are found in a biome.
Biomes, climate, and vegetation vary with latitude and altitude. Latitude is the distance north or south of the equator and is measured in degrees. Altitude is the height of an object above sea level.
Latitude and Altitude affect climate Gets colder the higher up you go (altitude) Gets colder the farther north/south of the equator you go (latitude) Most food on Earth is grown between 30-60 degrees north and south of the equator Biomes and Climate Latitude vs. Altitude
Climatograms Show average monthly values for temperature and precipitation. Temperature is expressed in degrees Celsius and is plotted as a smooth curve. Precipitation values are given in centimeters and are plotted as a histogram.
