英语翻译
1.Prey多,predator 食物充足,population增加
2.Prey少了,predator食物减少了,population减少;
3.predator少了,Prey又开始多起来了,如此循环population平衡.
实际上第三阶段就是第一阶段,因为是cyclic,不断重复这三个阶段

我去,楼上在干嘛呢,用维基百科忽悠人?
When prey increased,the food of predator will be sufficied consequently,hence its population raised.however if the prey decreased,the food of predator is going to cut down,hence its population reduced.cyclically the predator's decrease lead prey activate again,this circle makes the balance of predator's population.

维基上的解释,绝对标准而详细。
In ecology, predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked).[1] Predators may or may not kill their prey prior to feeding on them, but the act of predation always results in the death of its prey and the eventual absorption of the prey's tissue through consumption.[2] The other main category of consumption is detritivory, the consumption of dead organic material (detritus). It can at times be difficult to separate the two feeding behaviors[1], for example where parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on its decaying corpse. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat what is available and have no direct impact on the "donor" organism(s).
Selective pressures imposed on one another has led to an evolutionary arms race between prey and predator, resulting in various antipredator adaptations.
The unifying theme in all classifications of predation is the predator lowering the fitness of its prey, or put another way, it reduces its prey's chances of survival, reproduction, or both. Ways of classifying predation surveyed here include grouping by trophic level or diet, by specialization, and by the nature of the predator's interaction with prey.
