energy transfers

Question 1

why is NPP beneficial?

Answer 1

its the energy left over thats available to the plant to create new biomass and therefore available to the next trophic level in a food web.

Question 2

NPP: net primary production

Answer 2

the chemical energy store in plant biomass taking into account the energy that will be lost due to respiration (R)

Question 3

GPP: Gross Primary Production

Answer 3

the chemical energy store in plant biomass, in a given area or volume, the total area resulting from photosythesis.

Question 4

Net production of consumers equation:

Answer 4

N= I-(F+R)
I~ chemical energy store in ingested food
F~ the chemical energy lost to the environment in faeces and urine
R~ respiratory losses
