Tropical rainforest Carbon cycle Flashcards
1
Q
Vegetation storage stats
A
NPP (Net primary productivity) is very high
Averages 2500 g/m2/year
Biomass = 400/700 tonnes/ha
2
Q
What is NPP / how to calculate it?
A
NPP = Chemical energy store in plant biomass, after respiration has taken place.
NPP = GPP - R
3
Q
Soil storage stats
A
Low - Due to rapid cycling + leaching of nutrient
90/200 tonnes/ha
4
Q
Overall absorption of carbon
A
2.4 billion tonnes per year
