Biomes, Climate and Food Security Revision

What is a biome?

• A small ecosystem with diverse species

• A large geographic area with similar climate and life forms

• A specific habitat for a single animal species

• An ecosystem found only in tropical regions

List four different biomes.

• 1. Forest 2. Desert 3. Tundra 4. Grassland

• 1. Ocean 2. Mountain 3. River 4. Lake

• 1. City 2. Village 3. Town 4. Metropolis

• 1. Car 2. Bus 3. Train 4. Airplane

Describe how the Hadley Cell affects global climate patterns and name the two biomes most influenced by it.

• The Hadley Cell affects global climate patterns by controlling temperature and rainfall, with the most influence on tropical rainforests and deserts.

• The Hadley Cell affects global climate patterns by modifying ocean currents, with the most influence on tundra and grasslands.

• The Hadley Cell affects global climate patterns by changing wind directions, with the most influence on temperate forests and savannas.

• The Hadley Cell affects global climate patterns by altering soil nutrients, with the most influence on boreal forests and wetlands.

What is latitude?

• Latitude is the angular distance of a place north or south of the Earth's equator.
• Latitude is the distance from the North Pole to the South Pole.
• Latitude measures the height of a location above sea level.
• Latitude is the time it takes for the Earth to rotate on its axis.

Explain the role of latitude in determining the climate zones across Australia.

• Latitude influences temperature and precipitation patterns, which define the climate zones in Australia.

• Latitude has no effect on climate zones in Australia.

• Latitude only impacts climate zones in the southern hemisphere.

• Latitude is responsible for the geological features, which are the main factors in climate zones.

Food security refers to:

• The availability of food to all people at all times.

• The ability to produce food locally.

• The nutritional value of food.

• The affordability of food.

Explain the difference between food accessibility and food availability.

• Food accessibility refers to the affordability and convenience of obtaining food, while food availability refers to the physical presence of food in a location.

• Food accessibility refers to the physical presence of food in a location, while food availability refers to the affordability and convenience of obtaining food.

• Food accessibility and food availability both refer to the physical presence of food in a location.

• Food accessibility and food availability both refer to the affordability and convenience of obtaining food.

Explain how a failure of food accessibility and food availability can lead to food insecurity.

• A failure of food accessibility and availability can lead to food insecurity by reducing the ability of individuals to obtain sufficient and nutritious food.

• Food accessibility and availability failures have no impact on food insecurity.

• Food insecurity is solely caused by economic factors, not by food accessibility and availability.

• Food accessibility and availability failures only affect food prices, not food insecurity.

Is it environmentally responsible to cultivate rice in Australia, considering its status as one of the driest continents?

• Yes, because it boosts agricultural innovation.

• No, because it strains water resources.

• Yes, because it enhances food security.

• No, because it is not aligned with sustainable practices.

Identify the primary characteristics of a desert biome.

• High precipitation, moderate temperatures, and dense forests

• Low precipitation, extreme temperatures, and sparse vegetation

• Consistent rainfall, mild temperatures, and diverse wildlife

• Frequent snowfall, cold temperatures, and ice-covered landscapes
