Worksheet time: 30mins
Tropical rainforests and mangroves are found between the Tropic of Cancer and the Tropic of Capricorn.
True
False
Name the largest rainforest on the South American continent.
(a)
Identify the location of the Amazon Rainforest.
Tropical rainforests can also be found in these areas:
Southeast Asia
Europe
Congo Basin
Russia
Which of the following describes the tropical climate?
High annual temperature at an average of 27°C
High total annual rainfall of 2000mm on an average
High annual temperature range
No distinct wet and dry season
Tropical climate has a small annual temperature range.
True
False
Both the tropical rainforests and mangroves are EVERGREEN because:
Do not shed all of their leaves at particular times of the year.
They don't shed leaves.
Continuously grow new leaves to replace older ones that die and fall off, maintaining a constantly green appearance.
Which of the following explains why there is a wide biodiversity of plants and animals in the tropical rainforest?
High temperature and rainfall throughout the year enable a large variety of plants to grow and evolve.
There is human interference in the rainforests.
The large variety of plants supports the large variety of animals
For every 0.01 sq km of rainforest at the Amazon, there are about 300 known plant species.
True
False
Tropical rainforests are less dense and less luxuriant as compared to mangroves forests.
True
False
Trees in the tropical rainforests have to compete for sunlight as plants grow very close to each other.
True
False
What are the three main layers of the tropical rainforest?
Emergent
Canopy
Understorey
Shrub
Undergrowth
Many trees in the tropical rainforest can grow up to a height of 50m.
True
False
Label the three main layers in the tropical rainforest.
Match the height of the layers found in the tropical rainforest.
Emergent layer
more than 30 metres
Canopy layer
20 - 30 metres
Undergrowth layer
below 10 metres
Very little sunlight reach the (a) layer. Thus, not many plants are able to grow here except for the smaller ones that are able to grow in the (b) and the (c) of taller trees. When gaps in (d) appear, a lot of (e) can reach the undergrowth, and certain species of undergrowth plants are able to take advantage of this situation by growing upwards quickly and filling in the gaps.
Trees in the emergent layer have straight and smooth trunk with a lot of branches.
True
False
(a) roots support their heavy weight and height.
Buttress roots grow out from the base of the trunk to as high as 5m above the ground.
True
False
Most tropical rainforest trees are in the canopy layer.
True
False
The following describes the canopy layer:
Trees in this layer grow very close to one another
Crowns interlock to form a thick and near-continuous mass of branches and leaves
The canopy layer prevents 97-98% of the sunlight that the top of the tropical rainforest receives from passing through to reach the forest floor.
The trees in this layer are 30-50m tall.
The canopy layer blocks off most of the sunlight in the undergrowth layer.
True
False
There is dense vegetation in the undergrowth layer.
True
False
Trees and plants in the undergrowth layer can only grow well when there are gaps in the canopy layer.
True
False
Which of the following describe the leaves of trees in the tropical rainforest.
They are broad to absorb sunlight.
Waxy and leathery to reduce loss of water vapour.
The leaves have drip-tips to allow rainwater to fall off leaves easily.
Leaves need to be waxy with drip-tips to prevent bacteria growth.
Leaves of the trees in the tropical rainforest are (a) to absorb sunlight.
The leaves of the trees in the tropical rainforest have drip-tips to allow (a) to fall off leaves easily.
Leaves of the trees in the tropical rainforest need to be (a) with drip-tips to prevent bacteria growth.
