(1)此图中，不符合孟德尔遗传规律的遗传物质 32、下图中的甲、乙两图为-昼夜中某作物植株对CO2的吸收和释放状况的示意图。甲图是在春季的某一晴天，乙图是在盛夏的某一晴天，请据图回答问题：
甲 乙
(1)甲图曲线中C点和E点(外界环境中CO2浓度变化为零)处，植株处于何种生理活动状态?
____________________________________________________。
(2)乙图中植株积累有机物最多的是________________________点。
(3)乙图中FG段CO2吸收量逐渐减少是因为________________________，以致光反应产生的_________________________________逐渐减少，从而影响了暗反应强度。
(4) 在种植大棚蔬菜时，若遇到连续阴雨天气，适当降低棚内温度可防止大量减产，其生物学原理是__________________________________________________
