10、响。7 .在高山上，海拔越高温度越低，阔叶林分布在海拔较低的地方，针叶林分布在海拔较高的地方，说明 对植物分布的影响;沙漠上到处是不毛之地，只有靠近水源的地方出现绿洲，这说明 对植物分布的影响。8 .通过探究可以发现，光照会影响鼠妇、黄粉虫等动物的分布.温度会影响金鱼的呼吸。探究的一般过程包括> 、>(2)、在光对鼠妇生活的影响探究实验中，使这两种环境中除 #,湿度、温度等其他条件 都相同。也就是说，只有光照是不同的，光照就是这个实验中的 。(3)、在研究一种条件对研究对象的影响时，所进行的除这种条件不同以外，其他条件都相同的实验， 叫做 例如：探究“光对鼠妇生?S的影响”实验中，

11、设计 ? 网种环境，其他条件都相同，就是对照实验。(4)、做完实验后，要把小动物 在探究光对鼠妇的影响实验中为什么要 用10只鼠妇做实验而不能用一只？ 为什么要计算全班各组的平均值?9 .生物因素对生物的影响：生物和生物之间最常见的关系是： ，如七星瓢虫捕食财虫； 稻田中杂草和水稻争夺阳光、养料和水分 、例如 草盛豆苗稀； 例如蚂蚁、蜜蜂等昆虫往 往成百上千只生活在一起，组成一个大家庭，家庭之间分工合作。关系:例如菟丝子寄生在豆科植物的植株上，能寄生寄生在寄生于榆树、桦树、枫杨、梨树等树上；一些寄生虫常寄生在动物体 内。10 .蚯蚓在土壤中活动，可以使土壤疏松、“千里之堤毁于蚁穴”、“大树底下

12、好乘凉”描述的是11骆驼的尿液非常少、当体温升高到46c才会出汗、荒漠中的植物骆驼刺的根系非常发达、仙人掌的叶变成针刺状，是生物对 环境的适应；海豹的皮下脂肪很厚是对 环境的适应；旗形树的树 冠像一面旗帜是树对 的适应；经常刮风的海岛上昆虫的翅是残缺的或无翅的，是昆虫对风的适应。12.在一定的空间范围内，与 所形成的统一整体叫做生态系统。例如一片森林、一片草原、一块农田、一个湖泊、一条河流、等等都可以看作是一个个生态系统。Now , we ae i n a ne w his oIcI stgeof alr ound cnstucin of a wel off sociey.In pefm du
