Food Biomass Requirements calculates the mass of crops produced for human and animal consumption, quantities required for resource production and energy use calculations in other sections of the model. It comprises 3 procedures:

===(1) Crop Use for Human Consumption===
^Inputs^Outputs^
|//Canada total population// (person) from [[caness:demography:Population]] | //crop for person food// (tonnes/year)|
|//crop food per capita// (tonnes/(person*year)) |  |
Crop Use for Human Consumption takes //Canada total population// (person) from [[caness:demography:Population]] and //crop food per capita// (tonnes/(person*year)) to calculate //crop for person food// (tonnes/year). This is passed on to the calculators [[CanESS:foodProd:vegOilAvail|Recycled Vegetable Oil Available]] and [[CanESS:resourceDisp:agrLndBMDisp|Agriculture Land Biomass Disposition]].
===(2) Animals Fed===
^Inputs^Outputs^
|//animals per capita// (animals/(person*year))|//animal stock fed// (animals/year) passed to [[CanESS:foodProd:anFatAvail|Animal Fat Available]]|
|//Canada total population// from [[CanESS:demography:Population]]| |
Animals Fed uses //animals per capita// (animals/(person*year)) as well as //Canada total population// from [[CanESS:demography:Population]] to calculate the number of animals that require feeding. This is saved in the variable //animal stock fed// (animals/year) and is passed on to the calculator [[CanESS:foodProd:anFatAvail|Animal Fat Available]].
===(3) Animal Feed Required===
^Inputs^Outputs^
|//animal stock fed// (animals/year|//crop feed for animals required// (tonnes/year) passed to [[CanESS:energyUse:ResourcePrdEU:biomassPrdAEU:agrLndBMPrd:anFeedBS|Animal Feed Byproduct Substitution]]|
|//food per animal per year// (tonnes/animal)|//pasture feed for animals required// (tonnes/year) passed to [[CanESS:energyUse:ResourcePrdEU:biomassPrdAEU:agrLndBMPrd:anFeedBS|Animal Feed Byproduct Substitution]]|
| |//total animal feed required// (tonnes/year) passed to [[CanESS:energyUse:indNonFuelPrdSecEU:fertPrdEU|Fertilizer Production Energy Use]] and [[CanESS:emissions:anBasedEm|Animal Based Emissions]]|
Animal Feed Required uses //animal stock fed// (animals/year) from (2) Animals Fed along with the required //food per animal per year// (tonnes/animal) to calculate the required amount of animal feed. This information is saved in 3 variables:
  *//crop feed for animals required// (tonnes/year), which is passed on to [[CanESS:energyUse:ResourcePrdEU:biomassPrdAEU:agrLndBMPrd:anFeedBS|Animal Feed Byproduct Substitution]],\\
  *//pasture feed for animals required// (tonnes/year), which is also passed on to [[CanESS:energyUse:ResourcePrdEU:biomassPrdAEU:agrLndBMPrd:anFeedBS|Animal Feed Byproduct Substitution]], and\\
  *//total animal feed required// (tonnes/year), which is passed on to [[CanESS:energyUse:indNonFuelPrdSecEU:fertPrdEU|Fertilizer Production Energy Use]] and [[CanESS:emissions:anBasedEm|Animal Based Emissions]].
