A biome is a major region that is characterized by its climate, soil type(s), and the dominant plants, animals, and other organisms that live there.

A biome is made up of many individual ecosystems.

Climate

• Weather conditions over a long period of time

Latitude and Altitude Affect the Climate

Gets colder the higher up you go (altitude)

Gets colder the farther north/south of the equator you go (latitude)

Most of food on Earth is grown between 30-60 degrees north and south of the equator

-- Do we live in this latitude??--

Tundra

TundraArctic tundra can be found in

Antarctica and the North Pole, North of the Arctic Circle.

Grass, lichen and herbsPermafrost – layer of soil that is

always frozen.Very short warm season that is

very wetMany insects during warm

season

Coniferous Forest

Coniferous forestIs one of the most fragile biomesSpruce and Fir trees Found in Northern HemisphereGrowing season very shortNearly constant daylight in

summerMany lakes and swamps

Temperate Deciduous Forest

Temperate Deciduous ForestClimate and amount of sunlight

can vary tremendously between each season.

Deciduous trees lose their leaves in fall.

Grassland

GrasslandsGrasslands are characterized by their

tall, perennial grasses and lack of trees.

2 Types 1. Tropical grasslands: between the

Tropic of Cancer and the Tropic of Capricorn, hot year-round, very dry, season of heavy rain.

2. Temperate grasslands: north of the Tropic of Cancer or south of the Tropic of Capricorn, cold winters and hot summers.

Cover a quarter of the land on Earth

Desert

• Deserts take up 8.6 million square miles on Earth.

DesertGet less than 25 cm of rain each

yearHas little or no vegetationDriest places on earthOften located on the dry side of

mountain ranges

Tropical Rainforest

Tropical RainforestContain over half of the world's

plant andanimal species live here. All fit

into only7 percent of the world's land.

Found in: Central Africa, Southeast Asia,

Philippines, New Guinea, Central and South

America.

Tropical RainforestLayers:Top – Emergent layer – tallest

trees above rest of forestNext – Canopy – top of normal

treesLower canopy – epiphytes –

plants that grow on tree trunks – not soil - because light is so far from ground.

Understory – lowest level, much darker

ClimatogramsA climatogram is a graph that shows average monthly values for two factors: 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.
