Teacher background information<br />
NOTE: For the purposes of accuracy, this unit is titled ‘<strong>The</strong> rainforest’ instead of ‘<strong>The</strong> jungle’. This unit introduces animals and<br />
plants associated with tropical rainforests. All rainforests are jungles but not all jungles are rainforests.<br />
<strong>The</strong> world’s rainforests occur around the ‘waist’ of the globe, between the tropics of Cancer and Capricorn. Tropical rainforests are<br />
always hot and humid because they lie close to the Equator and have a lot of rainfall.<br />
<strong>The</strong> rainforests are home to millions of plant and animal species. <strong>The</strong> plants consume carbon dioxide and generate oxygen so<br />
rainforests are known as the ‘lungs of the planet’.<br />
<strong>The</strong> world’s major tropical rainforests are located in Central and South America, central Africa and Madagascar, Southeast Asia<br />
and the Cape York Peninsula of Queensland, Australia.<br />
Plants create different layers and habitats within the rainforest:<br />
<strong>The</strong> forest floor is the lowest layer. It is very dark, so there is little or no plant growth. Vegetation that falls decomposes very<br />
quickly. Many insects and small creatures can be found on the forest fl oor and up in the trees. Giant anteaters and other large<br />
creatures live there.<br />
<strong>The</strong> understorey receives a little sunlight so plants can grow here. <strong>The</strong>y have developed wide leaves to take in as much<br />
sunlight as possible. <strong>The</strong>se leaves create more shade on the forest fl oor.<br />
Emergent<br />
<strong>The</strong> canopy forms a roof over the layers beneath. It is a network of leaves and<br />
branches, teeming with life: insects, birds, reptiles and mammals.<br />
<strong>The</strong> emergent layer contains the tallest trees of the rainforest. Flying creatures such<br />
as birds, bats and butterfl ies are found here. Climbers such as monkeys can also<br />
reach these treetops.<br />
Canopy<br />
Plants are the most numerous living things in the rainforest, feeding the insects which<br />
in turn become prey to larger but less numerous creatures.<br />
<strong>The</strong> balance of nature in the rainforest is under constant threat from human activity.<br />
<strong>The</strong> extinction of a single species can create a hole in a food web and have a<br />
disastrous effect on an ecosystem.<br />
Some of the animals in various rainforests around the world, and their diet/prey, are<br />
listed on the facing page.<br />

Concepts to be developed<br />
• A tropical rainforest is found in the hot, humid parts of the world.<br />
• <strong>The</strong>re are four layers in the rainforest.<br />
• <strong>Rainforest</strong>s are home to many different plants and animals.<br />
• Plants and animals feed on each other to form a food web.<br />
