What is a Biome?
Biomes are Large scale ecosystems defined by abiotic factors.
1 of 31
What is an ecosystem?
An ecosystem includes all of the living things (plants, animals and organisms) in a given area
2 of 31
What is a living organism called?
Biotic
3 of 31
What is a non living organism called?
Abiotic
4 of 31
What is a producer?
An organism that uses sunlight energy to produce food.
5 of 31
What is a consumer?
An organism that gets energy from consuming other organisms
6 of 31
What is a Food Chain?
A diagram to show what eat what in a an ecosystem.
7 of 31
What is a decomposer?
An organism that gets energy from breaking down dead materials.

Tropical forest, Temperate forest, Boreal Forest, Grasslands, Desert, Tundra and Coral Reefs

What are the characteristics of a Tropical forest?
The tropical rainforest is a biome with a constant temperature and a high rainfall.
10 of 31
What are the characteristic of a Temperate Forest?
contain trees that lose their leaves and are found across Europe and USA. The weather is mild and wet.
11 of 31
What are the characteristic of a Boreal Forest?
Occurs in cold northern regions characterised by long cold winters and short summers
12 of 31
What are the characteristics of a Grassland?
located further away from the equator than the tropical rainforest biome in the central part of Africa and in South America.
13 of 31
What are the characteristics of a Deserts?
Deserts are hot during the day and cold at night.
14 of 31
What are the characteristics of a Polar ecosystem?
biomes are cold and treeless with very little precipitation.

Describe the Climate of a tropical rainforest?
In general, tropical rainforests have hot and humid climates where it rains virtually everyday. The level of rainfall depends on the time of year. Temperatures vary through the year - but much less than the rainfall.
16 of 31
Describe the soil profile of a tropical rainforest?
The soil isn't very fertile because all of the nutrients has been washed away.
17 of 31
Describe the nutrients cycle of a tropical rainforest?
Trees are evergreen, so dead leaves and other materials fall all year round. The Warm moist climate means that fungi decompose the dead organic material quickly. The material is soluble meaning it dissolves in to the soil. Taken by plants for growth.
18 of 31
Describe the water cycle of a tropical rainforest?
The roots of the plants take up the water and is stored in the plant. The water then falls on to the canopy due to the warm weather the water evaporates and causes clouds. This is convection rainfall.

Why is the rainforest important? (6 Reasons)
Carbon sink, Stabelies the world's climate, Provide a habitat for may plants and animals, Are a source of medicine and food, Supports tribal people and maintains the water cycle.
20 of 31
Explain how humans have an impact on the rainforest?
120 prescription drugs are deprived from the rain forest, Logging cause a loss of oxygen, Extinction of animals, Climate change and pollution from mining.

Describe the characteristics of the Antarctic
Continent covered by an immense ice cap and surrounded by the Antarctic Ocean Mountains up to 3,794 metres high Ice 4.5 km thick in places
22 of 31
Describe the climate in Antarctica.
Very cold due to lack of direct sunlight Temperatures average -28°C in summer and -60°C in winter Dry
23 of 31
Describe the Flora in Antarctica.
Almost no vegetation.
24 of 31
Describe the Fauna in Antarctica.
Penguins, seals and whales
25 of 31
Describe the characteristic of The Arctic
Not a land continent Ocean surrounded by continents with large islands, eg Greenland, Ellesmere Island Ice reaches height of 2 to 3 metres Sea pack ice
26 of 31
Describe the climate in the Arctic
Cold due to lack of direct sunlight - but not as cold as Antarctica Temperatures average 0°C in summer and -40°C in winter
27 of 31
Describe the Flora in The Arctic
Low shrubs, sedges and grasses, mosses and liverworts
28 of 31
Describe the Fauna in the Arctic
Polar bears, Arctic fox, reindeer and wolves Seals, whales and bird species
29 of 31
Explain how the part of the Antarctica ecosystem are linked.
There are no Flora so fauna have to rely on fish or small organisms from the sea.
30 of 31
How does human activity affect Polar regions?
The ecosystem is very fragile so any slight change in it could be catastrophic, If larger ship come then more people will arrive, Threats of oil spills and pollution from diesel generator and planes can affect the environment.
