(每空2分,共18分)根据下面的碳循环示意图回答问题:

说明: 6ec8aac122bd4f6e

(1)从微观上看,过程③主要是在细胞内                 进行的。

(2)碳从无机环境进入生物群落的主要途径①是         ;碳主要以    的形式从无机环境进入生物群落。

(3)参与过程④的生物新陈代谢类型是                              

它们与同区域中的动、植物共同构成了         

(4)太阳光能照射到地球表面后,大部分被吸收并通过各种方式转化为热量,热量最后以             形式再辐射;太阳光能在植物体内的转换过程为                                         

(5)碳循环的进行伴随着能量流动;但由于生物体不能在代谢中利用            ,因而能量流动具有                            的特点。

 

(1)线粒体(2)光合作用 二氧化碳(3)异养需氧和异氧需氧  生物群落(4)热(红外)辐射,光能---电能----活跃             的化学能---稳定的化学能     (5)热能  单向不循环 【解析】
