What do people mean, in a more philosophical sense, when we refer to predatory animals or apex predators as "strong" and to prey animals as "weak"? For instance, deer and elk can easily break the ribs of an attacking wolf, and deer and elk aren't necessarily easy to kill, but people think of wolves as strong while deer and elk are weaker. I'm not a science student, but I know enough science to know that apex predators are much more vulnerable than commonly thought and that it's more of a food web than a food chain. But wolves and lions are majestic and mighty while deer and rabbits are weak, easy prey. Can you help me to unpack the implied philosophies involved? Other than the Great Chain of Being, unless that's really what I'm looking for. I'm not looking toward the life sciences. Are there philosophical theories or schools of thought which consider strength and weakness in a sense that might be applicable to a predator/prey dynamic?
