• It has the greatest variety of lifeforms of any terrestrial biome

• All of the statements are correct

Characteristics of tropical rainforest:

• Rainforest trees are deciduous

• Rainforest trees are coniferous

Characteristics of tropical rainforest

The rainforest is stratified - it has different layers. The layers, in order from top to bottom, are...

• Herb, shrub, sub-canopy, canopy, emergent

• Emergent, canopy, sub-canopy, shrub, herb

• Canopy, emergent, sub-canopy, herb, shrub

• Canopy, emergent, sub-canopy, shrub, herb

Nutrient cycling

The biggest store of nutrients in the rainforest is the...

• soil

• litter

• biomass

Nutrient cycling in the tropical rainforest returns nutrients to the biomass store very __________

• slowly

• quickly

Nutrient cycling

The constant rainfall means that a lot of water infiltrates through tropical rainforest soils. As it trickles through the soil, the water takes nutrients with it.

Name this process:

• Runoff

• Weathering

• Leaching

• Decomposition

The food chain

The primary ___________ such as plants get their energy from the sun, these are then eaten by primary consumers (herbivores), which are then eaten by secondary consumers (carnivores), which are then eaten by tertiary consumers.

• vegetation

• producers

• consumers

• decomposers

Nutrient cycling

When an organism dies it is eaten by __________ and the nutrients are recycled

• plants

• producers

• microbes

• the Sun

Adaptations

Select the way(s) in which plants have adapted to the high levels of rainfall

• Thick waxy leaves

• A wide canopy

• Buttress roots

• Drip tips

Adaptations

Some animals have a good sense of smell or hearing because of the _________ intensity light levels on the forest floor.
