farms that can produce large volumes of food or fibre in a small area

This leaches important minerals out of the soil

This makes intensive farming difficult

Crop yield – the amount of crop (in kg) that is grown per hectare and is used by farmers to measure how much they have grown

strong winds can dry out the soil, and damage or even destroy crops

a nearby river or aquifer can provide water to irrigate crops or to give animals such as cows and sheep water to drink

many farmers in the developing world have few financial resources to buy machinery and hire labour and so they rely on their physical labour and are able to grow only enough foot to feed their own families

farmers often specialize in growing a certain crop or raising a certain breed of animals. This may have been the case for many previous generations. As a result, they may have built up great deal of expertise in this type of farming

A state where all people always have access to enough safe, nutritious food to sustain a healthy life.

a place is apart of earths surface that brings meaning to people. places can be natural or built

refers to the way are arranged on the earths surface

The living and non-living components and elements that make up an area, and the ways they are organised into a system

Geographers use this concept to better understand the links between places and people, and how these interconnections affect the environments and the way we live

recycling of paper by individuals

Australian Government has begun to encourage sustainable use of energy by offering incentives to promote the use of solar panels

organisations such as the Marine Stewardship Council are working with fisheries and retailers to promote responsible and environmentally viable fishing practices around the world

Helps us to understand what is happening around us and to see the world as a dynamic place

Scientists have developed the term Biome to describe areas on the Earth with similar climate, plants, and animals

North and south America, Africa, Middle East, Australia, and Asia

Cacti, small bushes, and short grasses. Desert plants are adapted to collect and store water, and reduce water loss

Animals adapted to intense heat and lack of water. Some animals never drink water, instead they get water from seeds and plants that they consume. Many animals are nocturnal so that they do not have to combat the sun’s heat

Grasslands are big and open spaces. There are not many bushes in the grassland. Trees are found only by rivers and streams

Many large herds of grazing animals such as zebras and bison. Animals live in herds for protection, because there are few trees and bushes to camouflage themselves

Near the equator. South America, Asia, Pacific islands, Australia, New Zealand, and Africa

Several varieties of exotic plants and animals. Lush green and vibrant colours.

Vines, palm trees, orchids, ferns. Most plants must compete for sunlight and nutrients due to their dense population. The majority of common houseplants come from the rainforest

Life inside the wet rainforest is bustling with slithering snakes and chirping birds. An animal must be both smart and strong to survive in this environment

Also known as a “coniferous forest”. Regions have cold, long, snowy winters, and warm, humid summers

Coniferous-evergreen trees (trees that produce cones). The trees are narrow and grow very close together. This is so they can help protect each other from the weather

Snow, cold, and a scarcity of food make life very difficult, especially in the winter. Some animals migrate south, other go into hibernation, while others simply cope with the environment
