Energy Flow and Ecosystem Services Flashcards
ecosystem services
any benefit we get from nature
Ecosystem services catagories
provisioning services
regulating services
cultural services
supporting services
provisioning services
products obtained
regulating services
water filtrations, carbon storage, pollination, decomposition
cultural services
non-material benefit (recreation, asthetics)
supporting services
basic functions (photosynthesis, nutrient cycling, soil formation)
primary productivity
the rate plants can convert CO2 to sugar or something else
net primary productivity =
gross primary productivity (photosynthesis - respiration (plant operating costs)
determinates of primary productivity
water availability
temperature
nutrient avalibility
soils
management
carbon storage is determined by _______ and ____________
carbon fixation, carbon loss
3 main carbon sinks
live plant material
microbial biomass
dead plants and microbes
restoration of degraded/harvested forests most effective in the _______
tropics
most effective strategy of forest restoration
allow forests to restore naturally
Why are grasslands a more reliable carbon storage than forests?
less vulnerable to wildfire and drought
ecosystem services tied to energy flow
primary producers
primary and secondary consumers
detrital feeders and decomposition
