a large scale ecosystem with similar plants, animals, soil and climate

Six major biomes• Taiga • Deciduous forest• Tropical rain forest• Desert• Tundra• Grassland

Tundra

TundraLocation: northern North America, northern Europe, northern Asia

Climate: Cold, ground stays covered in snow, permafrost – permanent frozen layer of ground, scarce rainfall, very short summer

TaigaLocation: Canada, Washington (State), Russia, China- Found only in Northern Hemisphere

Climate: long cold Winters, short Summers, frequent Rain

Plants: Evergreens (think Christmas Trees), Pines, Spruces, Cedars

Animals: Moose, Bear, Lynx, Hibernating Animals, Migrating Animals

Abiotic factorsWinters are long and cold

Averages 100 in/yr precipitation—mostly snow

Soil poor in nutrients and very acidic

Growing season is very short

Plant adaptations

Animal AdaptationsAdapt for cold winters

Burrow, hibernate, warm coat, insulation, etc.

Plant adaptations

Coniferous (needle-bearing) trees are abundant

Plant adaptations

Roots long to anchor trees

Plant adaptations

Needles long, thin and waxy

Plant adaptations

Needles long, thin and waxy

Low sunlight and poor soil keeps plants from growing on forest

Tropical Rain Forest

Tropical Rain ForestLocation: near the Equator, Africa, & South America

Climate: Hot and Humid, rains everyday

Plants: Jungle (think Tarzan), very tall trees, thick vegetation on the ground, dense canopy

Animals: parrots, Apes, Toucans, Monkeys, Leopards, other predatory Cats, Snakes

Earth's most complex land

Abiotic factors

high biodiversity and biomass

Abiotic factors

both hot and moist;

Abiotic factors

both hot and moist;

ideal for bacteria and other microorganisms; they quickly decompose matter on the forest floor allowing nutrients to be recycled.

Abiotic factors

both hot and moist;

<1 cm of topsoil

Abiotic factors

both hot and moist;

<1 cm of topsoil

About 100 in/yr of rainfall

Plant adaptations

Sunlight is a major limiting factor

Plant adaptations

Plants grow in layers (canopy receives most light)

Plant adaptations

Shallow, wide roots since soil is so thin and poor in nutrients

Plant adaptations

Little sun reaches the floor

Plant adaptations

Animal AdaptationsMany animals are specialists and require special habitat components to survive

Camouflage is common

Many symbiotic relationships

Live in different levels of canopy

Deciduous Forest

Deciduous ForestLocation: eastern United States (think about where we live), most of Europe, Australia

Climate: hot Summers, cold Winters, Rainfall throughout the year

Plants: Trees that lose their leaves, Maples, Oaks, Hickories, Sycamores, Willows

Animals: Bears, Foxes, Raccoons, Deer, Squirrels, Birds

Abiotic Factors Plant adaptations

Animal Adaptations

Characterized by an abundance of deciduous (leaf bearing) trees

Characterized by 4 seasons

Soils: Deep soil layers, rich in nutrients

Precipitation: 30–100 in/yr in all forms (snow, rain, hail, fog, etc.)

Abiotic Factors Plant adaptations

Animal Adaptations

Abiotic Factors Plant adaptationsDeciduous forests grow in layers

Animal Adaptations

More sunlight reaches the ground compared to a rainforest so you will find more ground dwelling plants.

Animal Adaptations

More diversity in the deciduous forest vs. the coniferous forest due to increased sunlight.

Animal Adaptations

Trees adapt to varied climate by becoming dormant in winter

Animal Adaptations

Lose Winter Coat

Animal Adaptations

Desert

Location: Africa, Middle East, parts of North America

Climate: Hot in the day and cold at night, little rainfall

DesertPlants: Succulent Plants (retain water in the leaves), Cacti, and small Shrubs

Animals: Lizards, Snakes, small Rodents, other Rodents

Abiotic factors

<10 in/yr of rain

Little to no topsoil due to high winds.

Minerals not deep in soil.

Too dry for decay

Desert Plant Adaptations:

• Spines

Marine (Salt Water)

Freshwater

Estuaries • Streams and rivers merge with ocean water in areas known as estuaries. • Estuary organisms experience changes in salt concentration and temperature as

the fresh water and salt water mix. • Estuaries serve as breeding grounds for many invertebrate and fish species, and

as nesting and feeding areas for a great diversity of birds. • Along most of the east coast of the United States, the major ecosystems found in

estuaries are salt marshes. • In tropical areas, the typical estuary ecosystems are mangrove swamps. • These swamps are dominated by mangrove trees, which are anchored by tangled

networks of arching roots.

• The area of shore between the high-tide and low-tide lines. • Pounded by waves during high tide and exposed to the sun and drying winds

during low tide, benthic organisms in this zone must be well-adapted to survive these harsh conditions

Intertidal Zone

Near Shore Zone • The area of the ocean from the low-tide line out to the edge of the

continental shelf. • Since the ocean here is fairly shallow, some sunlight reaches the

bottom in most of the zone. • As a result, many organisms that require light for photosynthesis can

live in this zone, including seaweeds and phytoplankton.

Open-Ocean Zone • The vast open ocean from the edge of the continental shelf outward. • Phytoplankton drifting near the surface are the major producers in this

zone. • Microscopic animals called zooplankton also inhabit this area and in turn

are a source of food for other animals.

Deforestation The removal of large amounts of trees for the resources those

trees or land provide

Reclamation The planting of new vegetation on land that has been previously harvested or

Strip Mining

The removing of earth's resources by removing layer by layer, this destroys the land and makes it impossible to replant.
