生物只有适应环境才能生存下来，如果不适应环境就会被______，生物对环境的适应不仅表现在形态和结构方面，还表现在______方面．猪笼草形似鲜花，能诱捕采蜜的小虫，猪笼草这种与其他生物相似的状态叫做______．
达尔文的进化论揭示自然选择的规律是“适者生存，不适者淘汰“．自然选择是进化生物学中最核心的概念，同时也是导致生物进化的关键因素．达尔文指出，生物都有很强的繁殖能力，又由于生物生存的空间与食物是有限的，所以生物就会因争夺生存的空间与食物而进行生存斗争，在生存斗争中，适者生存，不适者被淘汰的过程就叫自然选择．因此生物只有适应环境才能生存下来，如果不适应环境就会被淘汰，生物对环境的适应不仅表现在形态和结构方面，还表现在生理和行为方面，如鸟类的迁徙．猪笼草形似鲜花，能诱捕采蜜的小虫，猪笼草这种与其他生物相似的状态叫做拟态．
故答案为：淘汰；生理和行为；拟态．
