海洋食物网
Description
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
Mastery Evidence
- 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
Assessment Prompt
Can your child explain why catching too many of one type of fish doesn't just affect that fish — it affects the whole food web, including the animals that eat it and the things it eats?
