2 What is a Biome?The earth is covered by many different types of ecosystemsScientists group similar ecosystems into Biomes.A biome is a large area with a specific climate and certain plants and animals.
3 There are 10 main land biomes Polar iceTropical rainforest*Temperate forest*Taiga*Tropical savannaTemperate grassland*Chaparral*Desert*Tundra*Mountains
4 Biomes and Vegetation (plants) Biomes are described by the plants that grow in them because the plants determine what animals will live therePlants in a biome will all have characteristics that allow the plants to survive better in that biomeThese characteristics include size, shape and color
5 Biomes and Vegetation (plants) cont. Ex. A cactus that lives in the hot desert does not have leaves because leaves let out water. In a hot desert having leaves would mean the cactus would dry out and die
6 Biomes and Climate Climate refers to weather conditions like: temperaturerainfallhumiditywindTemperature and rainfall are the 2 most important factors
7 Temp. and Precip.The climate of a biome is determined by it’s average temperature and it’s average amount of rainfall.Most organisms have a certain temperature range that they can live in.They also must live in an area that gets enough water to keep them hydrated.
8 Latitude and AltitudeBiomes, climates and the things that live there change with latitude and altitude.Latitude is how far north or south of the equator you are.As your latitude increases you get farther from the equator which means there is less direct sunlight and the climate gets colderAltitude is how high above sea level you are.It also gets colder as the altitude increases (as you go up a mountain)The colder climates change the plants that grow there.
