=== Assistant: 對!你抓到重點了 👍 === 對!你抓到重點了 👍 生物的確不是單一層級,而是分很多「層級」和「複雜度」。 一般來說,科學把生命系統從簡單到複雜分層: # 微觀層級 - 病毒:介於生命與非生命之間,必須依賴宿主才有「生命活動」。 - 原核生物:像細菌(Bacteria)、古菌(Archaea),沒有細胞核,結構簡單。 - 真核單細胞生物:如變形蟲、草履蟲,有細胞核,比細菌複雜。 # 多細胞層級 - 植物、動物、真菌:由許多細胞組成,細胞分工合作(有的負責能量轉換,有的負責運動)。 # 群體層級 - 群落或社會性生物:例如螞蟻、蜜蜂、白蟻,人類社會,這些已經不只是個體,而是整個群體像一個超級「生命系統」。 所以可以想像: * 病毒是在邊界遊走的「準生命」。 * 細菌是最簡單的「完整生命」。 * 人類或動物則是高度複雜的生命。 * 整個生態系統也可以看作是「更大一層級的生命」。 🤔 要不要我用「金字塔圖」的方式幫你整理,從病毒到人類甚至到整個生態系,顯示這種「生物層級」?
