Ocean Food Webs
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
Suggested ages 7–9
Learning journey
Your child is diving deeper into ocean science — learning how sea creatures are classified, understanding complex ocean food webs, and exploring the different zones and features of our vast oceans.
Evidence of understanding
- 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 Ocean Food Webs 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?
