=== Predictions === There are three key predictions from the field processing model.

The amount an individual is willing to process is proportional to traveling time. This is evident in

      x
      
        0
      
    
  

{\displaystyle x_{0}}

and

      x
      
        1
      
    
  

{\displaystyle x_{1}}

in the equation above. Since

      x
      
        1
      
    
  

{\displaystyle x_{1}}

is the amount of time it takes an individual to process something to an additional stage, and this is independent of the amount of time it takes one to initially procure the resources, and since

      x
      
        1
      
    
  

{\displaystyle x_{1}}

is positive, then increasing it will result in an increase in

    z
  

{\displaystyle z}

. If processing results in a greater benefit, then one will not need to travel as far to make processing worthwhile. This is clear to see because, as long as condition 2 holds,

      y
      
        1
      
    
  

{\displaystyle y_{1}}

is larger than

      y
      
        0
      
    
  

{\displaystyle y_{0}}

. So that part of the equation will be negative. Therefore, if we hold everything else the same and increase the benefit due to processing, the travel time required to make processing viable will decrease. Field processing can increase the amount of time that an individual is willing to pursue a prey. If processing a prey item results in a big enough benefit, you will spend longer capturing it. We can see this by looking at where

      x
      
        0
      
    
  

{\displaystyle x_{0}}

is in this model. Since it interacts with the benefit due to processing, a change in either of those can alter

    z
  

{\displaystyle z}

. Central place foraging predicts that foragers will optimize their routes and resource collection strategies based on the distance and profitability of resources relative to their central location, aiming to maximize their energy gain while minimizing travel costs. Processing efficiency may vary based on environmental conditions, such as resource abundance or scarcity, influencing the overall foraging strategy. Transport decay curves demonstrate the reduction in return rates (cal/hour) experienced by a central place forager as a function of round trip travel time.
