Questions and Answers

What is the purpose of drip tips on leaves in the rainforest?

To provide shade for the plant

Study Notes

Rainforest Adaptations

Drip tips on leaves in the rainforest serve to remove excess water, reducing fungal growth and promoting water runoff.

Epiphyte Nutrient Acquisition

Epiphytes in the rainforest obtain their nutrients from the air, rain, and debris that collects on their leaves and stems.

Buttress Roots

Buttress roots in the rainforest provide stability and support to trees on shallow, nutrient-poor soils.

Root Systems

Trees and plants in the rainforest have shallow, spreading roots to absorb nutrients from the soil.

Gersmehl Model: Nutrient Stores

In the Gersmehl model, the biomass nutrient store is described as huge in tropical rainforests.
The biomass nutrient store is the largest due to the rapid growth and high biomass production in tropical rainforests.
The soil nutrient store is relatively small in tropical rainforests because nutrients are quickly absorbed by plants or lost through leaching.
The litter nutrient store is small in tropical rainforests because of rapid decomposition and nutrient cycling.
