Crabtree and associates produced an electronic food internet that catches all categories of customers and consumed, can be specified for specific time durations, and can also stand for food internet after significant food resources or killers vanish from the location. If a location all of a sudden becomes lacking deer or people or corn, for instance, a food internet of that circumstance can show where killers mosted likely to find victim, or which victim thrived for lack of a predator.
These knockout food webs—webs missing out on a specific predator or prey—show the changes and stress on the food resources replacemented for the missing out on ones, or the changes that occur when stress is removed by removing a significant customer.

People bringing corn right into a location is a significant interruption of the current food internet. Growing corn means clearing areas to displace whatever plants and pets existed, producing a high-energy grow resource of food and switching grow eaters to the preferred higher-calorie food resource.

To make up for this, they started to domesticate turkeys for food. Turkeys need to be fed corn if they are captive which takes on corn for human consumption. Currently, corn comprised 70 to 80 percent of Genealogical Puebloans' food therefore feeding turkeys altered the food internet.
