蜜蜂群体中有蜂王、雄蜂和工蜂,它们分工合作,共同维持群体生活。这种行为属于

A.社会(群)行为

B.攻击行为

C.防御行为

D.繁殖行为

答案

答案:A

题目分析:社群行为是群体内形成了一定的组织,成员间有明确分工的动物群集行为,有的还有等级.蜜蜂群体中有蜂后、雄峰、工蜂,蜂后只有1个主要职责是交配产卵、繁殖后代和统管这个群体大家庭;雄蜂数量较少,有发达的生殖器官,主要职能是与蜜后交配;工蜂数量最多,主要职责是建造和扩大保卫巢穴、采集花粉花蜜、饲喂幼蜂和蜂后等,蜜蜂需要彼此配合、密切合作才能维持群体的正常生存.因此蜂群中蜂王、雄蜂和工蜂,它们分工协作、共同维持群体生活的行为属于社会行为.
