2025 選修生物IV CH4-3 初級生產力與生態塔能量學

深入闡述生態學中的兩個核心概念：初級生產力與生態塔之間的密切關聯。將光合作用者比作生態系的「中央銀行」，說明淨初級生產力（NPP）是生態系可供消費的能量基礎，並詳細區分其測量單位和總生產力的差異。接著介紹兩種主要的生態塔類型——能量塔和生物量塔，並解釋能量塔因熱力學第二定律而永遠正立的原因。最關鍵的部分在於，它透過周轉率的概念，解釋為何在某些水域生態系中，生產者的生物量塔會呈現倒立的結構，強調初級生產力的速率（流量）決定了生態塔的規模與形態。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/a1a3838aecab Powered by Firstory Hosting
