# Biology maths question Watch

1. Hey, the question is this, the diagam shows the fate of food energy consumed by a sheep. All units are MJ day^-1

basically the diagram shows that consumption is 28.41. From this, respiration is 10.14 and faeces and urine is 12.97. Production is unknown.

I answered the first part fine, but the one im stuck on is,
(ii)calculate the efficiency with which energy in plant food is transferred to energy in new tissue in the sheep

You know that GPP = NPP - R(respiration)

Thanks, it looks like you just worked out the percentage of the production energy being used, is that right? Plus I dont know what the bit in bold means......
