- A. To absorb nutrients from the upper soil layers
- B. To provide structural stability in shallow, nutrient-poor soils

- B. Rafflesia arnoldii
- C. Bromeliads
- D. Pitcher Plants
In the context of rainforest soil, what does the term 'oxisols' typically refer to?
- A. Highly fertile volcanic soil
- B. Highly weathered soils rich in iron and aluminum oxides
- C. Peat-rich soils found in swampy areas
- D. Sandy soils with high drainage capacity
The 'Strangler Fig' begins its life as an epiphyte. How does it eventually 'strangle' its host tree?
- A. By secreting toxins through its leaves
- B. By absorbing all the sunlight with a faster growth rate
- C. By sending aerial roots downward that encircle and compress the host trunk

Which of these processes describes the recycling of nutrients from dead organic matter back into the living biomass almost instantaneously?
- A. Nitrogen Fixation
- B. Rapid Decomposition
- C. Transpiration
- D. Eutrophication
What is the primary reason why many rainforest plants have 'drip tips' on their leaves?
- A. To attract pollinators with water droplets
- B. To shed excess water quickly to prevent mold and algae growth
- C. To channel water directly to the root system
- D. To increase the surface area for photosynthesis
Which of these is a characteristic of the 'Emergent Layer' of the rainforest?
- A. Low light levels and high humidity
- B. The presence of the most diverse fungal networks
- C. Trees that tower above the canopy, exposed to high winds and intense sun

- B. Mutualism
- C. Parasitism
- D. Amensalism
The 'Transpiration' process in rainforests contributes to a phenomenon known as 'biotic pumping'. What does this mean?
