问题 选择题

下列体现社会行为的是

A.雄狒狒争夺首领

B.猎豹追捕羚羊

C.乌贼释放墨汁

D.蜻蜓点水

答案

答案:A

题目分析:动物营群体生活,绝不是同种的许多个体简单的聚集在一起,而是动物之间存在组织,具有明确的分工和森严的等级制度,如狒狒营社会行为,在各个组成成员之间,根据个体大小、力量强弱、健康状况和凶猛程度,排成等级次序,其中只有一个雄性个体最占优势,其为社群中的首领,优先享有食物和配偶,优先选择筑巢场地,其他成员对它表示顺从,负责指挥整个社群的行动,并且和其他雄狒狒共同保卫这个群体,所以存在明显的等级制度,而猎豹追捕羚羊一种是捕食行为,乌贼释放墨汁属于一种防御行为,蜻蜓点水是一种繁殖行为。
