- Biotic - the living part of the biosphere
- Altitude - how high something is
- Atmosphere - a mixture of gases surrounding the Earth
- Decay - rot or decompose
- Biomass - biological material derived from living or reently living organisms
- Biome - a formation of plants and animals that have similar charcateristics
- Biosphere - the 'living layer' of the Earth
- Climate - the weather conditions in a certain area
- Latitude - the distance of a place North or South of the equator
- Natural Resources - materials or substcnces occuring in nature
- Urbanisation - the increase in the proportion of people living in towns and cities
- Flora - plants Fauna - animals
- Abiotic - the non living part of the biosphere
- Factors Affecting Biome Distribution
- Rock and Soil Type - affects how fertile different areas are in a biome
- Altitude - different plants grow at different temperatures
- Rainfall - different plants will grow with different amounts of rainfall
- Ocean Currents
- Atmospheric Pressure Belts
- Wind
- Distance from the sea - this affects the temperature and amount of rainfall
- Drainage - few plants grow in boggy areas
- Proximity to the Poles
- Latitude
- Rock and Soil Type - affects how fertile different areas are in a biome
- Valuing the biosphere
- the biosphere is valued at roughly $4-6 trillion per year
- Goods - physical materials
- Services - a function or role
- the biosphere is valued at roughly $4-6 trillion per year
- Goods and Services
- Goods
- Fish, Meat, Fruit, Nuts, Berries
- Drugs to cure diabetes and drugs to fight cancer
- Plants used to make general medicines
- Timber, bamboo, rubber, water, oil and gas

- Trees absorb Carbon Dioxode
- Indiginous people live in the Rainforest as they have done for centuries
- >50% biological diversity on Earth found in tropical rainforest
- Holidays
- Nutrients for soil
- Help control the hydrological cycle
- A home for endangered animals
- Goods
- Increase of demand for resources
- Larger/Increasing Population - there's more people using up the resources

- Overfishing
- Deforestation
- Malthus and Boserup
- Graph Showing the Contradicting Views
- Malthus believed the population would grow so large we wouldn't have enough resources
- Boserup Believed that we would invent new ways of gaining resources and would be fine
- Graph Showing the Contradicting Views
- Role of the Biosphere regulating...
- the Carbon Cycle
- it regulates the gases that make up the atmosphere by plants absorbing C02 and giving out Oxygen
- it regulates the gases that make up the atmosphere by plants absorbing C02 and giving out Oxygen
- Hydrological Cycle
- plants slow the flow of water to rivers and filter water
- plants slow the flow of water to rivers and filter water
- Nutrient Cycle
- Rotting plant material provides new nutrients for plants to grow
- Rotting plant material provides new nutrients for plants to grow
