Chapter 2.4BIOMES

Target 1 BIOME

• I will identify the main factors that are used to determine a biome.

a) Climate which is based on: Temperature Precipitation

Target 2 BIOMES

• I will research the six major biomes on Earth1- Rainforest2- Desert3- Grassland4- Deciduous Forest5- Boreal Forest6- Tundra

Target 3 BIOMES

• I will illustrate a study guide to identify the main characteristics of each biome.

1- Temperature range – daily and annually2- Precipitation range – daily and annually3- Main animal life4- Main plant life

Target 4 BIOME

• I will understand where Biomes fit in the Organization of Living Things in an Ecosystem

Organization of Living Thingsreview

• Individual Organism – a species

Organization of living thingsreview

• Population – a group of all the same species.

Organization of living thingsreview

• Community – a group of populations in the same region.

Organization of living thingsreview

• Ecosystem – interaction of the Abiotic and Biotic factors.

Organization of living things• Biome – A group of land ecosystems with

similar life forms and climate.

BIOME• Each Biome has its own similar plants and

animals.

Rainforest parrot

Arctic fox Pine trees African elephant

BIOMES• Each Biome has a similar climate

Tundra

Desert Rainforest

BIOMES• CLIMATE is the main factor used to identify a specific

biome. CLIMATE = temperature (T*) and precipitation(P )

Tundra

Desert Rainforest

BIOMESThere are six (6) major biomes• Rain forest • Desert • Grassland• Deciduous forest• Boreal forest• Tundra

BIOME - Rainforest1) Rain forest There are two types of rain forest Tropical rain forest – hot, humid, and has the largest variety of life forms.

BIOME - Rainforest1) Rain forest There are two types of rain foresto Temperate rain forest – cooler, less humid,

and has a large variety of life forms. over 300 cm rain per year

BIOME - Desert2) Desert• Receives less than 25 cm of rain per year.

BIOME - Desert2) Desert• Receives less than 25 cm of rain per year.• Climate: Has the largest daily temperature

change. Scorching days frigid nights.

BIOME - Desert2) Desert• Receives less than 25 cm of rain per year.• Climate: Has the largest daily temperature

change. Scorching days frigid nights.• Living organisms must adapt to limited water.

BIOME - Desert2) Desert• Receives less than 25 cm of rain per year.• Climate: Has the largest daily temperature

change. Scorching days frigid nights.• Living organisms must adapt to limited water.• Plants: cactus• Animals: lizards, small mammals

BIOME - Grassland3) Grassland – there are two types

BIOME - Grassland3) Grassland – there are two typesa. Savannah – located near the equator

BIOME - Grassland3) Grassland – there are two typesa. Savannah – located near the equatorb. Prairie – located further from the equator

BIOME - Grassland3) Grassland – there are two typesa. Savannah – located near the equatorb. Prairie – located further from the equator• They receive 25-75 cm rainfall per year.

BIOME - Grassland3) Grassland – there are two typesa. Savannah – located near the equatorb. Prairie – located further from the equator• They receive 25-75 cm rainfall per year.• Not enough rain to support tree growth

BIOME - Grassland3) Grassland – there are two typesa. Savannah – located near the equatorb. Prairie – located further from the equator• They receive 25-75 cm rainfall per year.• Not enough rain to support tree growth• Plants: Rich soil supports tall grasses

BIOME - Grassland3) Grassland – there are two typesa. Savannah – located near the equatorb. Prairie – located further from the equator• They receive 25-75 cm rainfall per year.• Not enough rain to support tree growth• Plants: Rich soil supports tall grasses• Animals: Some of the largest animals on Earth

BIOME - Deciduous4) Deciduous forest • Have trees that lose their leaves each autumn.

BIOME - Deciduous4) Deciduous forest • Have trees that lose their leaves each autumn.• At least 50 cm rain per year

BIOME - Deciduous4) Deciduous forest • Have trees that lose their leaves each autumn.• At least 50 cm of precipitation per year• Support a wide variety of habitats

BIOME - Deciduous4) Deciduous forest • Have trees that lose their leaves each autumn.• At least 50 cm rain per year• Support a wide variety of habitats• Climate: Seasonal temperature changes

BIOME - Deciduous4) Deciduous forest • Have trees that lose their leaves each autumn.• At least 50 cm rain per year• Support a wide variety of habitats• Climate: Seasonal temperature changes• Plants: oaks, maples, shrubs, grasses, mosses

BIOME - Deciduous4) Deciduous forest • Have trees that lose their leaves each autumn.• At least 50 cm rain per year• Support a wide variety of habitats• Climate: Seasonal temperature changes• Plants: oaks, maples, shrubs, grasses,• Animals: must cope with seasonal temperatures

BIOME - Deciduous4) Deciduous forest • Have trees that lose their leaves each autumn.• At least 50 cm rain per year• Support a wide variety of habitats• Climate: Seasonal temperature changes• Plants: oaks, maples, shrubs, grasses,• Animals: must cope with seasonal temperatures BY: Tolerating , Migrating , Hibernating

BIOME - Boreal5) Boreal forest (taiga)• Conifers = trees that do not lose their leaves

(needles) in winter such as pine, fur, spruce, and hemlock.

BIOME - Boreal5) Boreal forest (taiga)• Conifers = trees that do not lose their leaves

(needles) in winter such as pine, fur, spruce, and hemlock.

• Climate: Winters very cold, Summers very cool.

BIOME - Boreal5) Boreal forest (taiga)• Conifers = trees that do not lose their leaves

(needles) in winter such as pine, fur, spruce, and hemlock.

• Climate: Winters very cold, Summers very cool.• Plants: mosses, grasses, shrubs, dwarf trees

BIOME - Boreal5) Boreal forest (taiga)• Conifers = trees that do not lose their leaves

(needles) in winter such as pine, fur, spruce, and hemlock.

• Climate: Winters very cold, Summers very cool.• Plants: mosses, grasses, shrubs, dwarf trees• Animals: Small herbivores , carnivores, insects

BIOME - Tundra6) Tundra• Climate: Extremely cold and dry

BIOME - Tundra6) Tundra• Climate: Extremely cold and dry• Soil is frozen all year called Permafrost

BIOME - Tundra6) Tundra• Climate: Extremely cold and dry• Soil is frozen all year called Permafrost• Plants: mosses, lichens, grasses, dwarf forms

BIOME - Tundra6) Tundra• Climate: Extremely cold and dry• Soil is frozen all year called Permafrost• Plants: mosses, lichens, grasses, dwarf forms• Animals: insects, birds, mammals

Mountains & Ice Mountain ranges are not part of any biome. The climate changes as you go from the base to the

summit of a mountain. As you go up you will pass through a series of

different biomes.
