5.
Which statement best describes Net primary productivity?
The total dry mass of living material at a trophic level.
Eats plants / eats animals / eats both.
Makes its own food from inorganic sources — photosynthesis or chemosynthesis.
GPP minus the energy producers use in respiration — what is available to consumers.
6.
Producers fix 12 000 kJ (GPP) and use 4 500 kJ in respiration. What is the net primary productivity?
16 500 kJ
7 500 kJ
4 500 kJ
12 000 kJ
7.
An animal ingests 500 kJ and passes 200 kJ as faeces and urine, and respires 250 kJ. Its net production is:
300 kJ
250 kJ
50 kJ
450 kJ
8.

Net primary productivity is

GPP plus respiration
energy absorbed by the leaf
GPP minus respiratory losses
energy in decomposers
