Behavioral Ecology Using the Model Food choice 1 is scarce, but is highly profitable, meaning it will yield a high amount of energy with a low handling time. E/h for food 1 is therefore quite high. However, because we are trying to maximize both E/h and E/t, we must also take into account the time it takes to find the very scarce food choice 1. Food choice 2 is abundant, but less profitable than food 1. E/h for food source 2 is not very high, but it takes much less effort and time for the animal to find food choice 2. The model assumes the animal is holding food 2, meaning that there is no search time involved for food choice 2 since the animal has already found it. The animal stands over the food and must debate whether to eat it: is the immediate consumption of food choice 2 a better action than moving on and looking for some of that fine food choice 1? We can put this debate into mathematical terms: If E2/h2 > E1/(s1 + h1) then the animal should eat food 2.
