Which Biome, Where?Comparing Land and Water Environments on Earth
Key Objectives:
The student will:– Investigate and Understand
the differences between ecosystems and biomes
Key Objectives:
The student will: – Differentiate between
ecosystems and biomes
Key Objectives:
The student will:– Investigate and Understand
the characteristics of land (terrestrial), marine (salt water) and freshwater biomes
Key Objectives:
The student will:– Compare and contrast the biotic
and abiotic characteristics of major land, marine and freshwater biomes
Key Terms
Biome Marine Biome Freshwater Biome Tundra Desert Grassland Dormancy
Tropical Rain Forest Taiga (Evergreen
Forest) Temperate Deciduous
Forest Hibernation Migration
Biome
Large geographical regions with similar climates, plant and animal life
Land Biomes (Terrestrial)
TundraTaigaTemperate Deciduous
ForestTropical Rain ForestGrasslandsDesert
Tundra
A terrestrial biome characterized by its frost-molded landscapes. It is the coldest of all the biomes.
Tundra
Tundra comes from the Finnish word tunturi, meaning treeless plain
Taiga (Evergreen Forest)
A terrestrial biome characterized by forest covered with coniferous trees (Pine Trees).
Taiga (Evergreen Forest)
The taiga is the largest terrestrial biome in the world.
It covers large parts of Canada, Europe, and Asia.
Temperate Deciduous Forest
More precisely termed temperate broadleaf forest
Temperate Deciduous Forest
A terrestrial biome characterized by having a temperate climate and that most of the trees lose their leaves in the winter
Rich dark soil from years of leaf decomposition
Tropical Rain Forest
A terrestrial biome characterized by its hot, moist environment it is found near Earth's equator.
Tropical Rain Forest
Though only about 6% of the earth’s land surface. It is earth's most complex biome in terms of both structure and species diversity.
Desert
A terrestrial biome characterized little rainfall and dry barren landscapes. It covers about one fifth of the Earth's surface
Grasslands
Covers over 20% of the earth’s surface. Large areas of the North America called the
prairie. Also located in central Europe and central Asia
In Africa it is called the savannah Deep rich soil excellent for farming
BREAK
Aquatic Biomes
The Marine Biome The Freshwater Biome
Marine Biome
Makes up the largest percentage of aquatic biomes on earth.
These biomes are extremely important to how our earth currently functions.
Marine Biome
These biomes involve a medium to high percentage of salt in the water
Freshwater Biome
An aquatic biome that accounts for less than one fifth of the area of the Earth.
Freshwater Biome
It provides half of the drinking water, one third of the water used for irrigation.
Support Terms
Hibernation
A behavioral adaptation observed in some organisms which live in colder climates where the organism slows down and sleeps out the cold season
Migration
The instinctive movement of animals such as birds moving south for the winter
Dormancy
The time of year when plants do not appear to be living (brown grass in Winter)
When a seed has not yet germinated
Adaptation
An evolutionary change that allows a species to survive in a particular environment.– Hummingbirds long beak for extracting
nectar– Penguins are flightless birds but use
their wings to swin
Lab Time
Now it is time to introduce the new lab.
Pease open your Green lab guides to page1
Read the introduction silently as I read it aloud
Essential Learnings
Regions of the world located at similar or opposite latitudes often have similar climates and ecosystems
These are called Biomes
Essential Learnings
There are six (6) terrestrial biomes– Tundra– Taiga (Evergreen Forest)– Temperate Deciduous Forest– Tropical Rain Forest– Grassland– Desert
Essential Learnings
There are two (2) aquatic biomes– Marine – Freshwater
Essential Learnings
Climate is defined as the typical long-term weather pattern found in an area over time
Essential Learnings
The tilt of the earth on its axis combined with its revolution around the sun play a major role in the climate of any region
Essential Learnings
Climate factors:– Precipitation– Temperature– Altitude– Latitude
Essential Learnings
Climate may also be affected by nearby large bodies of water, high altitude and a “rain shadow effect” of a mountain range.
Essential Learnings
Regions of the world located at similar or opposite latitudes often have similar climates and tend to have ecosystems with similar dominant plants and animals
Essential Learnings
Organisms adapt to their environments
Natural Selection is the process where the best suited organisms for the environment survive and the less suited do not
Essential Learnings
Adaptations may be:– Structural (physical features)
Beak sizeLoss of flight but ability to swim (penguins)
Essential Learnings
Adaptations may be:– Behavioral
HibernationMigration
Essential Learnings
Many plants go dormant periods of cold and low sunlight or during the harsh winter season
They come back/revive every spring.
