This layer of the rainforest is between 30 - 40m tall. Hardwood, evergreen trees that have broken through the dense canopy layer below to reach the sunlight here. Monkeys and birds live up here. What layer of the rainforest am I?

• Emergent Layer

• Canopy Layer

• Understorey Layer

• Forest Floor

This layer of the rainforest is between 20 - 30 m. The dense layer is home to trees snakes, birds, tree frogs and other animals because there is so much food available. What layer of the rainforest am I?

• Emergent Layer

• Canopy Layer

• Understorey Layer

• Forest Floor

This layer is between 10 - 20 m and contains young trees and those with large leaves, to capture sunlight; huge numbers of insects here. What layer of the rainforest am I?

• Emergent Layer

• Canopy Layer

• Understorey Layer

• Forest Floor

This layer of the rainforest is between 0 - 10 m. The darkness of this layer means shade-loving ferns with large leaves live here along with mammals like the jaguar. What layer of the rainforest am I?

• Selective logging

• Big tree logging

Select the two inputs into the nutrient cycle...

• Weathering

• Decay

• Leaching

• Precipitation

Which is the largest nutrient store in the tropical rainforest?

• Biomass

• Litter

• Soil

The transfer arrow growth is the largest in the tropical rainforest nutrient cycle, why is this?

• There are no seasons so plants grow all year round

• There are seasons so the rain helps plants to grow

• People are planting more trees because of deforestation

• There are more species of plant, so more growth

Since most nutrients in the tropical rainforest are stored in biomass, if forest is cut down most nutrients are destroyed. This has two effects:

• Increased surface run off

• Land cannot be farmed for long because of reduced nutrients

• Increase in precipitation

• Increase in weathering
