2025 bilogy talkshow : 漫談能量轉換效率 (選修生物4)

from 雷比特生物空中講 · host 雷比特老師

闡述生態系統中能量傳遞的原理及其效率損耗的奧秘。透過將能量傳遞過程細分為三個關鍵階段進行解釋:消費效率(CE),指食物被攝取的比例;吸收效率(AE),衡量食物被消化吸收的程度;以及生產效率(PE),表示吸收能量轉化為生物量的比例。每一階段都伴隨著能量的流失,特別是脊椎動物因維持體溫而耗費大量能量,導致整體能量轉換效率顯著降低,平均僅約10%。這種逐步遞減的能量傳遞機制解釋食物鏈長度的限制以及頂級掠食者數量稀少的原因,強調自然界能量流動的有限性。 聽完後可以自主進行線上測驗,檢視學習成效喔~(需要登入gemini) 測驗網址   https://g.co/gemini/share/2b12a917c610 Powered by Firstory Hosting
