Biomes Basics
What is a biome?
A large area with similar plants, animals, and climate.
What is Australia’s largest biome?
Desert.
Crop yield refers to the total amount of crop produced per unit of land, such as tonnes per hectare. True or False?
True. Crop yield measures how much crop is produced from a certain area of land, which helps farmers and researchers evaluate the productivity of agricultural systems.
What is the better AFL team in WA?
West Coast Eagles
Cutting down trees is called what?
Deforestation.
Which two things mainly decide a biome?
Temperature and rainfall.
In which biome do we grow wheat?
Grassland.
What is irrigation and why is it used?
Artificially supplying water to crops—to overcome rainfall variability and boost yields.
The polar bear resides in which biome?
Arctic Tundra
What happens if we use too much water on farms?
Soil gets salty / waterlogged.
Why does a rainforest have more species than a desert?
More rain and stable warm climate give better growing conditions.
Why are tropical biomes good for sugarcane?
Warm temperatures and high rainfall help it grow.
Why do farmers irrigate crops?
To give water when rain is not enough.
If Person A moves his cattle for grazing across different regions depending on weather and climate conditions, he is known as a what farmer?
Nomadic farmer
How does crop rotation help the soil?
Different crops stop nutrients being used up and reduce pests.
Which biome usually lies between deserts and forests?
Grasslands.
Why is Tasmania mostly temperate forest?
It has cooler temperatures and more rain than mainland Australia.
Why do farmers use fertilisers, and what is one problem if too much is used?
Helps plants grow, but too much can pollute rivers and soil.
The Amazon Rainforest is the home to 10% of all known species on Earth. True or False?
True
What happens to biodiversity when forests are cleared?
Animals lose homes, species numbers drop.
Explain one way latitude influences biome distribution.
Distance from the equator affects solar energy and climate, producing predictable bands of biomes.
How did Indigenous fire use help the land?
It encouraged new plant growth and created habitats for animals.
What is the difference between intensive and extensive farming?
Intensive uses small areas with lots of inputs (e.g., vegetables); extensive uses large areas with fewer inputs (e.g., sheep grazing).
How can the war in Ukraine impact food prices at home?
Disruption to the global food supply chain
How might climate change affect Australian farming?
More droughts and heat waves make it harder to grow crops.
