energy transfer and productivity Flashcards
why cant plants absorb all sunlight
light misses the chlorophyll molecule
what is NPP
the potential food availible to consume in the eco system
how much energy typically transfers through the tropic levels
10%
why does not all the energy pass from one trophic level to another
some is lost as heat through respiration
what is GPP
total chemical energy in a plants biomass in a given area
what is GPP in relation to trophic levels
the amount of energy avalible for the next trophic level to consume
give three ways of which energy is lost
through heat from respiration
through urine
through not digesting the bones and fur
what is the equation for the NET production of consumers
n=I-(F+R)
what is secondary production
the rate at which energy is used to make new organic molecules within heterotrophs
what is the equation for efficancy
energy available after transfer/energy avalible before transfer x100
in the equation for the NET production of consumers what does I stand for
chemical energy of ingested food
in the equation for the NET production of consumers what does F stand for
lost faeces and urine
in the equation for the NET production of consumers what does R stand for
lost in respiration
