3
What is a key feature of aquaponics systems in relation to water conservation?
Inefficient water use
Only viable in areas with excess rainfall
Recirculation between fish and plants
High water consumption
4
What is the primary reason for water scarcity in some parts of Australia?
Lack of infrastructure investment
Inefficient irrigation techniques
Over-extraction of groundwater
Arid climate and variable rainfall
5
What is a defining feature of tiered water pricing systems?
Industrial use = cheaper water
Higher usage = higher price
Exclusive to developing countries
Equal price regardless of usage
6
What is the connection between consumerism and water consumption?
High consumerism leads to higher consumption due to manufacturing needs
Consumerism has minor impact compared to population growth
No impact on consumption
Consumerism affects consumption in developing nations
7
Which of these best describes the relationship between living standards and water usage?
Higher standards = lower usage
No direct relationship

Affects industrial use
Sets household usage limits
Allows buying and selling of water allocations
9
What is the primary ecological function of natural wetlands?
Habitat for species
Reducing freshwater supply
Water purification and recharge
Decreasing groundwater levels
10
How does physical water scarcity differ from economic water scarcity?
Physical = arid areas, economic = wealthier nations
Physical = low density, economic = high density
Physical = demand exceeds supply, economic = unaffordable water
Physical = unaffordable, economic = demand exceeds supply
