Metabolism 2

Page under construction.

This is a slight variation of the Metabolism article. I introduce a Eat Ground action (which is not part of the default behaviour):

• The Move action is modified to be less effective in getting Energy from the ground (only 40% of the eaten Ground Food is converted in Creature Energy).
• The Eat Ground action is used instead, where 100% of the eaten Ground Food is converted in Creature Energy (but weighted by the metabolism factor).
• The Eat Creature action remains unchanged.
