LS2B - 生态系统中物质与能量转移的循环


Lice Science Disciplinary Core Idea 2B: Cycles of Matter and Energy Transfer In this video Paul Andersen explains how matter moves from the environment into living organisms and back into the environment. Food webs are used to show how matter and energy move through organisms. Ecological pyramids show that matter and energy are lost as they move from producers to consumers.

下一代科学标准生活科学纪律核心思想2B:
物质和能源转移循环
在这个视频中,Paul Andersen解释了如何将环境从环境中移动到生物体中并回到环境中。食物网用于展示如何通过生物体移动和能量。生态金字塔表明,随着从生产者到消费者的迁移,物质和能量都会丢失。
