What is a biome?
Biomes are sometimes referred to as ecosystems. Biomes are places that share a similiar climate and life forms.
What are the five distinct biomes across Earth?
Why are grasslands important?
Grasslands are the most useful biome for agriculture because the soils are generally deep and fertile. They are ideally suited for growing crops or creating pasture for grazing animals.
What are some characteristics of grasslands?
-a grassland biome is dominated by grass and generally has few or no trees .
-they are found in temperate and tropical areas.
-the rainfall is between 250mm and 900 mm per year.
What are grasslands used for?
Grasslands have been used for livestock grazing and are increasingly under pressure from urbanisation.
What major food grains are grown in a grassland biome?

Since European settlement, most native grassland has been removed or changed by farming and other development. Vast areas of grassland were cleared for crops, and introduced grasses were planted for grazing animals such as sheep and cattle.
What are wetlands?
Wetlands are biomes where the ground is saturated, either permanently or seasonally.
What are some reasons why wetlands are important?
-wetlands are a highly productive biome
-they provide important habitats and breathing grounds for a variety of marine and freshwater species.

-a natural filtering system and help purify water or filter out pollutants before they reach the coast.
-regulate river flow and stabilise the hotline
What 4 things do all wetlands have?
What are seagrass meadows?
-are covered by water all the time

What are mangroves?
-have pneumatophores that trap sediment and pollutants from the land and sea

-store water and release it slowly into the ecosystem
-have leaves that decompose and provide a food source for marine life
-provide shelter, breeding grounds and a nursery for marine creatures and birds
What are salt marshes?
-covered by water several times per year
-provide decomposing plant matter which is an additional food source for marine life
-have high concentrations of salt
What are the benefits of coral reefs?
-source of food for people:(
-protect coastlines from storms, erosions
-provide habitats and nursery grounds for fish
-source of new medicines
What are some threats to coral reefs?
-contamination by fossil fuels
-predators such as crown of thorns starfish
-urban development which increases erosion
-tourism; people on boats or dropping anchors
What is the difference between a fringing reef and a barrier reef?
A fringing reef grows upward from a volcanic island that has sunk entirely below se level, an atoll is then formed. A barrier reef when is growing is separated from land by an expanse of water. This creates a lagoon of open, often deep water between the reef and shore.
What are main major classification groups?
-wetlands and rivers
Why is soil important in different biomes?
Soil is important in determining which plants and animals inhabit a particular biome.
What are the major influences on climate?
The major influences on climate are the geographical features of the Earth's surface, such as mountain ranges and latitude.
Why is climate a major influence on biomes?
Temperature and rainfall patterns across the Earth determine what plant and animal species can survive in a particular biome.
What is biosphere 2?
Biosphere 2 is a research facility in the Arizona Desert, and has been designed to investigate Earth's life systems.
What are some examples of staple foods?

Fuel that comes from renewable sources
Why is wheat a good staple food?
It can be stored for a long time.
Why is fish a good staple food?

The Huli people live in rainforests of the Papua New Guinea.
How do the Huli people live?
The Huli clear a patch of rainforest and plant crops of sweet potato, sugar cane, corn, taro and green vegetables. When the soil of the garden no longer produces good crops, a new patch of rainforest is cleared, leaving the old one to recover naturally. The garden crops are supplemented by food that the men have hunted.
