Biomes • Earth has SEVEN major biomes:

• Marine

• Tropical rain forest

• Grassland

• Desert

• Temperate deciduous forest

• Tundra

• Taiga

Aquatic Biomes

• Covers about 75% of the Earth's surface

• Freshwater and saltwater

• Wide variety of animals and plants

Saltwater • The marine biome is the

biggest biome in the world!

– It covers about 70% of the earth.

• Includes oceans, coral reefs,

and estuaries(river flows into

ocean).

• Five main oceans: the Pacific,

Atlantic, Indian, Arctic &

Southern, as well as many

smaller Gulfs and Bays.

Tropical Rain Forest • Location: the Amazon in

South America, Central Africa, mainly involving Zaire, & Southeast Asia.

• Warm temperatures all year • 68 F-93 F

• Abundant rain fall all year • 150 cm per year (177 in)

• 49 in per year in Ga

• Soil is thin & lacks nutrients.

Rainforest Plants

• Lush, thick forests

• Canopy consists of uppermost branches of trees

• Trees have short roots

• Plants grow on trees to get sunlight

Orchids

Rainforest Animals • Home to

more than half of the world’s animals

• Range from tiny insects to large mammals

Grassland • Located: Africa, South America, Eurasia, and the plains of North America

• Hot summers & cold winters • Temperatures range from 100 F to -

40 F.

• 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer

• Soils that are nutrient-rich from the growth and decay of deep, many-branched grass roots

Grassland Plants • Primary plant life is grass

• Trees & large shrubs are largely absent

cm a year

– North America=almost 28 cm a year

• Soils are coarse-textured, shallow, rocky or gravely

Desert Plants • Plants have long roots & the ability to collect &store

water

Barrel Cactus Popcorn Flowers

Desert Animals • Nocturnal animals live in deserts, they come out at night to

avoid the high temperatures
