Animals eat a wide variety of food, sometimes taking a relatively large amount of time in handling the prey, an activity that includes capturing, killing, eating and digesting the food, and sometimes a relatively short amount of time. Probably, the reason behind such behavior is that animals make feeding choices based on the goal to maximize their net energy intake per unit time, leaving them with more time and energy for other important activities such as finding a mate or caring for an offspring; for instance, __________________________
A) some species of insects are ultimate feeding specialists, feeding only on a single plant species, whereas certain animals such as the opossum eat everything from insects and berries to garbage
B) using their biological reaction to a certain food item as a guide, some animals sometimes make the decision to avoid a particular prey altogether.
C) animals spend more time on handling food items that provide more kilocalories, and less on food that provides relatively fewer kilocalories.
D) under the risk of predation, animals sometimes select such preys that may not be their first choice but that are safer to consume as these preys lie in relatively predator free regions.
E) the foraging behavior of animals is determined by the phenomenon of natural selection in which certain biological traits become either more or less common as a species goes through the process of evolution.
