Study Notes
- Study notes on population growth effects on food production, biomes, human alteration of biomes and environmental and technological factors on crop yields in Australia and the world.
Food Security
- Involves locating and classifying countries by food security level.
Changes in Food Production
- Include soil and water management and pest control, used in Australia and globally.
Key Terms
- Biomes: Regions distinguished by climate, soils, vegetation, and productivity.
- Ecosystems: A biological community of interacting organisms and their physical environment.
- Biosphere: The regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms.
- Hydrosphere: All the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds.
- Atmosphere: The envelope of gases surrounding the earth or another planet.
- Lithosphere: The rigid outer part of the earth, consisting of the crust and upper mantle.
Biome and Ecosystem Characteristics
- A biome is characterized by distinctive climates, soils, vegetation, and productivity.
- An ecosystem is a community of living organisms interacting with each other and their environment.
Major Biomes
- Identifying and locating the world’s major biomes is essential.
General Biome Characteristics
- Include rainforests, deciduous and evergreen temperate forests, grasslands, tundra, and deserts.
- Distribution factors include climate and soils.
Human Use of Biomes
- Includes farming and forestry.
Human Alteration of Biomes
- Involves vegetation clearance, water usage, and terracing.
Farming Systems in Australia
- Identifying and locating the types of farming systems that occur in Australia is important.
Intensive vs. Extensive Agriculture
- Intensive agriculture: A type of agriculture, both of crop farming and animal husbandry, with higher levels of input and output per unit of agricultural land area.
