NAME THAT BIOME!
This biome is hot, wet, densely vegetated and found near the equator.
Tropical rainforest
What TWO climate factors are especially important in creating different biomes?
Temperature and rainfall
Which biome is most heavily relied upon for food production?
Grasslands
Name ONE technology used in modern farming.
e.g. machinery, irrigation, GPS, sensors, automation/robotics
Name ONE human activity that changes biomes.
Farming, logging or building
This extremely cold biome has no trees and may have permanently frozen ground.
Tundra
What is solar insolation?
The amount of solar energy reaching Earth's surface
Name TWO foods produced by tropical rainforest biomes.
Any 2: bananas, cocoa, coffee
What does agricultural yield refer to?
The amount of agricultural production/output
What is deforestation?
Removal/clearing of large areas of forest
This biome has tall grasses, scattered trees and distinct wet and dry seasons.
Savanna
Why are tropical rainforests generally found near the equator?
Direct sunlight/solar energy and high rainfall create hot, wet conditions
Name THREE factors that influence biome productivity for food production.
Climate, soil quality, water availability, biodiversity, armed conflict and/or adaptability
Give TWO ways technology can increase agricultural yields.
e.g. control water/nutrients, reduce pests, cultivate larger areas, monitor crops, improve crops/livestock
Give ONE environmental consequence of deforestation.
Habitat loss, soil erosion, water problems etc.
Compare a biome with an ecosystem. What is the main difference?
Scale: a biome is very large and contains many ecosystems; an ecosystem is a local interaction of living and non-living things
Why might a mountain have different vegetation from nearby lowlands?
Height/altitude affects environmental conditions such as temperature, creating different conditions for plants
Why are deserts and tundras generally less suitable for food production?
Their extreme climates limit plant/crop growth
What is commercialisation of agriculture?
The shift from producing mainly for household consumption to producing agricultural products for sale and profit
Explain how fertiliser runoff can damage the Great Barrier Reef.
Fertiliser enters waterways and can cause algae blooms and coral death
Australia's rainforests are mainly found on the well-watered eastern side of this major physical feature.
The Great Dividing Range
Explain how latitude influences the global distribution of biomes.
Latitude affects the amount of solar energy received, which influences temperature/climate and therefore the plants and animals that can survive
Explain why water shortages are a challenge to food production.
Less water is available for irrigation/livestock, reducing crop yields and food production and potentially increasing food prices
Give ONE benefit AND ONE limitation of using technology to make farming more sustainable.
Benefit: higher yields/less water or fertiliser/more efficiency. Limitation: expensive/requires skills/energy/inaccessible to smaller farmers
Explain how commercial agriculture can increase food production but reduce biodiversity.
Greater investment/intensive farming can raise yields, but clearing, monoculture, pesticides, grazing and other practices can reduce habitats/species diversity
