Biome Basics
What is a biome?
What is a large area on Earth with similar climate, plants and animals.
What are the two main crops grown in Australia for export?
What is wheat and cotton.
What is land degradation?
What is the decline in the quality and productivity of land.
What does ‘food security’ mean?
What is having reliable access to enough affordable, nutritious food.
What does the term ‘sustainability’ mean?
What is meeting present needs without compromising future generations’ ability to meet theirs.
Name two major terrestrial biomes.
What is - Examples: Desert, Forest, Grassland, Tundra, Savanna.
What human activities have altered natural biomes for agriculture?
What is clearing forests, irrigation, fertiliser use, grazing, and crop farming.
What is the main cause of deforestation in the Amazon?
What is clearing land for cattle ranching and soy farming.
Name one region of the world currently facing food insecurity.
What is Sub-Saharan Africa, South Asia, etc.
What is one global initiative promoting sustainable food systems?
What is The United Nations Sustainable Development Goals (SDG 2: Zero Hunger).
What factor primarily determines the type of biome found in an area?
What is climate (temperature and rainfall).
What is monoculture farming?
What is growing a single crop type in a large area.
How does deforestation contribute to climate change?
What is increasing CO₂ in the atmosphere by removing carbon-absorbing trees.
List one environmental factor that affects food security.
What is drought, floods, climate change, or soil degradation.
How can consumers support sustainable food production?
What is buying local, reducing waste, supporting organic farming.
Which biome is found near the equator and has the highest biodiversity?
What is Tropical rainforest.
Explain one negative impact of irrigation on natural systems.
What is salinity, waterlogging, and depletion of groundwater.
Explain the term “soil salinity”.
What is water dissolving salts and brings them to the soil surface, reducing fertility.
How does population growth impact food security?
What is increases demand for food, putting pressure on resources.
Give one example of how technology supports sustainable agriculture.
What is precision farming, drones for crop monitoring or renewable energy in farming.
Describe one way altitude can affect a biome’s characteristics.
What is higher altitude = cooler temperatures and different vegetation zones.
Give one example of sustainable farming practice.
What is crop rotation, organic farming, reduced tillage or integrated pest management.
Describe one strategy to reduce land degradation.
What is reforestation, terracing, crop rotation or contour ploughing.
Explain one technological solution improving food security.
What is drought-resistant crops, drip irrigation, vertical farming, etc.
Explain how climate change may affect the distribution of biomes.
What is changing temperature and rainfall patterns may shift biome boundaries.
