Energy and ecosytems

HideShow resource information
give ways in which energy is lost in a food chain
heat energy lost via respiration, energy lost via waste(faeces), energy lost in urine
1 of 7
Give reasons why not all energy is passed from a producer to a primary consumer
woody tissues and some roots which are not eaten, heat energy lost via digestion in the consumer, not all chemical energy is digested and absorbed by consumer (cellulose)
2 of 7
Give reasons why only about 3% of solar radiation enters a food chain
green light reflected off the surface of the leaf, some light missing leaves entirely, light energy passing through the plant and not trapped by chlorophyll molecules,
3 of 7
construct an equation involving Gross primary production, net primary production and respiration and give the units
NPP = GPP - R units = kJ m-2 year-1
4 of 7
why are enrgyy loses from mammals significantly greater than those of other organisms
they have to regulate their own body temperature therefore much more heat energy is lost via respiration
5 of 7
definition of detritivore
An animal which feeds on dead and waste matter
6 of 7
definition of detritus
dead and waste matter which is not eaten be consumers.
