ingenergyandrespirationreleasingitforuse.解析：本题考查生物能量获取方式。植物作为自养生物，通过光合作用利用光能合成有机物，这是地球上绝大多数能量的最初来源。动物作为异养生物，通过摄食植物或其他动物获取有机物，并在消化道内分解为小分子。细胞呼吸是动物获取能量的主要方式，通过有氧或无氧途径将葡萄糖等有机物氧化分解，释放能量并合成ATP。这一过程体现了生态系统中能量流动的规律，即能量在食物链中逐级传递并逐级递减。7.参考答案：Aleafiscomposedofseveralparts:theblade(thebroad,flatpart),thepetiole(thestalkconnectingthebladetothestem),andveins(whichtransportwater,nutrients,andsugars).Thebladecontainschloroplasts,wherephotosynthesisoccurs.Theupperepidermisistransparentandallowslightpenetration,whilethelowerepidermishasstomataforgasexchange.Veinsdistributewaterandnutrientsfromthestemandtransportsugarstootherpartsoftheplant.解析：本题考查叶片的结构与功能。叶片是植物进行光合作用的主要器官，具有典型的结构层次。叶片通过表皮细胞吸收二氧化碳，表皮上的气孔是气体交换的门户。叶
