ECOLOGY QUESTION: The 2 questions are on the bottom right of the picture.

Faced with a variety of potential food choices, predators must make decisions. Which types of food to eat? Where and how Iong to search for food? But how are these decisions made? Do predators function opportunistically, pursuing prey as they are encountered, or do they make choices and pass by potential prey of lesser food quality (energy content) while continuing the search for more preferred food types? If the objective is to maximize energy intake (energy gain per unit time), a predator should forage in a way that maximizes benefits (energy gained from consuming prey) relative to costs (energy expended). This concept of maximizing energy intake is (he basis for models of optimal foraging.

Explanation / Answer

1.

That depends on the time as well

If the time is short, then gull will continue the search, if the time is long, gull capture and consume the chiton.

2.

Searching and catching depend on the two parameters

1. Energy, 2. Searching time

So depends on the proportionality the event will take place
