lu1b game tropical rainforest Flashcards
characteristics: temperature
- year round warmth
- 20c - 34c
characteristics: average rainfall
2000mm - 4000mm
characteristics: humidity
average (77% - 88%)
characteristics: soil
acidic soil with leaching and poor nutrients
characteristics: similarity
- bark similarity among trees
( - don’t branch out for more than 30m - many tress can only be identified by their flowers)
characteristics: rain forest lie
where
near the equator
characteristics: season
brief dry season or monsoonal season
characteristics: how many layers of the rainforest
four distinct layers
characteristics: the 4 layers of the rainforest are
- emergent layer [60m above]
- canopy [40m from underground]
- understory (lower canopy) [3.5m or more] [only 2-5% sunlight]
- forest floor [0-2% sunlight] [100% humidity]
characteristics: diversity
high diversity of plants and animal
characteristics: major trees type
dominance of dipterocarpaceae trees “dipterocarp forest”
adaptations: tree bark
- smooth thin bark
- no need to protect them from water loss and freezing temperature
- allow water to flow down to the roots easily
adaptations: leaves
drip tip leaves (or oily coatings = rapid shedding of water, prevent branches break)
(keep them dry and prevent mold and mildew forming in the humid environment)
adaptations: roots
buttress roots (increase surface area, inhale more CO2 and release more O2; breathing)
adaptations: types of plant
carnivorous and heterotroph plants (cavity filled with either sweet or terrible smelling nectar that attract insects)
