Resource Management Flashcards
What are biotic factors?
Living organisms found in an area.
What are abiotic factors?
Physical, non-living environment like water.
What is renewable energy?
Energy that can be replenished as it is used.
What is non-renewable energy?
Energy sources that, once used, cannot be replenished and reused.
What is exploitation?
The use of a resource in a non-sustainable way.
What is overgrazing?
Rearing too many animals on land so that the roots are eaten. This means that the plants cannot regrow, leaving the soil bare.
How is water being used for exploitation?
Fresh water is used excessively for leisure and agriculture or extraction of minerals.
When minerals are extracted, toxic by-products can be washed into rivers.
In many countries rivers are used for disposal of sewage.
How is food being used for exploitation?
Farming - Land has been used to produce food for thousands of years but with an increasing population, land is being overgrazed.
Fishing - people take fish from the ocean to feed, this disrupts the food chain.
If land is overgrazed, soil is bare and exposed causing it to erode.
Many tropical rainforests have suffered from deforestation.
Overfishing has led to a reduction of biodiversity.
How is energy being used for exploitation?
The extraction of fossil fuels to produce energy can cause a number of problems.
They can produce sulphur dioxide, causing acid rain, carbon dioxide, causing the greenhouse effect and carbon monoxide, which can lead to suffocation.
What is a fossil fuel?
A naturally occuring fuel like coal, oil and natural gas formed from the remains of dead organisms.
What are natural resources?
Materials that are provided by the Earth that can be used to make something they can use.
What is distribution?
How something is shared out or spread across an area.
What is arable farming?
Growing of cereal crops,
What is pastoral farming?
The rearing of sheep, cattle, pigs or any other animals on a farm.
What is mixed farming?
A farm which has cereal crops and animals.
