海洋食物网
Ocean Food Webs
理解海洋食物网：由多条相互连接的食物链组成，能量从浮游植物（生产者）流向浮游动物、小型鱼类和大型捕食者；移除其中一个物种会影响整个食物网。
Understand ocean food webs: multiple interconnected food chains where energy flows from phytoplankton (producers) through zooplankton, small fish, and large predators, and that removing one species affects the whole web
学习证据 / Evidence
- 区分食物网和简单的食物链
- 至少追踪两条能量在海洋食物网中流动的路径
- 解释如果食物网中的一个物种被移除，可能会发生什么
- Distinguish a food web from a simple food chain
- Trace at least two paths of energy through an ocean food web
- Explain what could happen if one species in the web were removed
