1·Predator prey models play a crucial role in bioeconomics, that is the management of renewable resources.
在生物经济即可更新资源管理中，捕食系统起着非常重要的作用。
2·Prey species, like young deer or goats, for example, typically play by performing sudden flight movements and turns, whereas predator species, such as cats, practice stalking, pouncing, and biting.
比如说，像小鹿或者山羊这种被捕食的种群，它们的代表动作就是突然快速逃跑的动作和突然转弯；相反的，猫科动物之类的捕食种群会练习潜行追踪、猛扑和撕咬等动作。
3·At night, the pit organs allow snakes to "see" an image of their predator or prey-- as an infrared camera does-- giving them a unique extra sense.
在夜晚，窝器能让蛇类“看到”捕食者或者猎物的图像——正如红外摄影机一样——赋予他们一个独特的额外感官。
4·When experimental populations are set up under simple laboratory conditions, the predator often exterminates its prey and then becomes extinct itself, having nothing left to eat.
当实验种群在简单的实验室条件下建立起来时，捕食者往往会消灭它的猎物，然后自己也走向灭绝，因为没有东西可以吃。
5·Low prey population levels then provide inadequate food for the predators, causing the predator population to decrease.
较少的猎物数量为捕食者提供了不足的食物，导致捕食者数量减少。
6·The elements of intelligence and consciousness come together marvelously to produce different styles in predator and prey.
智慧和意识的元素奇妙地结合在一起，在捕食者和猎物身上产生了不同的风格。
7·Parasitism is a kind of predator-prey relationship in which one organism, the parasite, derives its food at the expense of its symbiotic associate, the host.
寄生是一种捕食者与被捕食者之间的关系，寄生者利用共生伙伴——宿主来获取食物。
8·In this situation, the predator and prey population may continue in this cyclical pattern for some time.
在这种情况下，捕食者和被捕食者可能会在一段时间内继续这种循环模式。
9·This unexpected display of color startles or confuses the predator and provides the would-be prey with an opportunity to escape.
这种意想不到的颜色表现会吓到捕食者或使其迷惑，并为潜在的猎物提供逃跑的机会。
10·And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover.
当一种猎物变得稀有时，如果捕猎者能够转向其他更容易找到的物种，这种转变可以让原来的猎物数量得到恢复。
