An infraclass is consumed (0) when the amount that gets used is lost in the process (this is true for food and consumer goods; it might also be true for other classes too).
Because the definition of a infraclass unit is arbitrary, in the input section I have made costs in commodities all sum up to 1, but that is not necessary (like the cost of services always being 1).
The rest of the money pertaining to each infraclass goes then to new units, the number of which is such that the remaining money can pay for their input and output (buying and usage).

As it is prescribed in the econ model, infraclasses resemble storage containers, where "units" are put in and out each turn, according to the amount of investment, consumption, destruction and decay that is applied upon them by the people's decisions and the game rules.
The rest of the money partaining to each infraclass goes then to new units, the number of which is such that the remaining money can pay for their input and output (buying and usage).
Infraclasses should definitely be on a 1 to 1 connection with tech tags.

Females then find the threads and pick up the spermatophore with their genitalia.
In the infraclass Pentazonia, order Glomerida, the spermatophore is deposited on a clump of earth, both of which are transported backwards to the telopods, which deposit the sperm directly into the female's openings.
In the infraclass Helminthomorpha, insertion is accomplished by the "gonopods." As they are on segment 7, males must first "charge" or "load" them with sperm by bringing them into contact with the openings to their reproductive tracts on segment 3.

The abstract of an article called "Topography, structure and function of the patella and the patelloid in marsupials" says: the subclass of placental mammals (Eutheria)
I note that most templates for placental orders, families, etc. refer to Placentalia alone, but if we need Eutheria as a group, then surely Placentalia is a subgroup of that, not an entirely seperate taxon as implied at present?
