请指出以上设计步骤中的错误并加以改正。
课后练习与提高
1、种群是指一定环境中（）A．同种生物所有成熟个体的总和B．所有生物成熟个体的总和
C．同种生物所有个体的总和D．所有生物个体的总和
2、下面是对某种双子叶草本植物种群密度的取样调查，操作步骤正确的是（）
①确定调查对象②选取样方③计数④计算种群密度

A.选取多种植物为调查对象
B.随机选取大小相等的若干块方形地块为样方
C.计算各样方内的平均值
D.样方内各年龄段的植物均需统计
4、按一对夫妇一两个孩子计算，人口学家统计和预测，墨西哥等发展中国家的人口翻一番大约20—40年，美国需要40—80年，瑞典人口将会相对稳定，德国人口将减少。预测人口的这种增减动态主要决定于（）A．种群数量和密度B．种群年龄结构

思考完成：年龄组成
当种群中青年的个体较多，年老的个体较少是，种群呈增长型，种群密度将会越来越大、当种群中年老的个体较多，而中青年个很较少是，呈衰退型，种群密度将会越来越小，当种群的个年龄段个体数相当时，呈稳定型，种群密度将会在一定时间内处于相对稳定的状态。
增长型稳定型衰退型

（三）：探究草地某双子叶植物的种群密度
1、单子叶草本植物常常是丛生或蔓生的，从地上部分难以辨别是一株还是多株，而双子叶植物则容易辨别是一株还是多株，而单子叶植物的叶子一般呈条形或是披针形，叶脉一般是平行脉，双子叶植物的叶子一般是网状脉。
2、细线、铁钉若干、皮尺、实验报告纸
3、①随机取样②样方的面积一般定在1m2
4、略
次数一次二次．…..
样方编号 1 2 3 4 5 6 7 8
样方计数
平均值
（6）略
（7）略
(四)①死亡率②出生率③性别比例④年龄组成原因：因为出生率和死亡率影响着年龄组成：当出生率大于死亡率时，年龄组成为增长型；当出生率约等于死亡率时，年龄组成组成为稳定型；当出生率小于死亡率时，年龄组成为衰退型。面出生影响着性别比例，而死亡率不会影响性别比例。
四、当堂训练：1.D 2.C 3.A 4.D

6、①选取面积应为100cm×100cm
②应随机选取5个样方
③应为N1到N5 的平均值
