Ocean Ecosystems

Understand ocean ecosystems as interconnected systems where living things (producers, consumers, decomposers) and non-living factors (temperature, salinity, light, currents) all interact, and that changes to one part affect the whole system

How to tell they’ve got it

Tick these off as you see them — no test required.

Describe an ocean ecosystem as a system of living and non-living parts that interact
Name key non-living factors that affect ocean life: temperature, salinity, light, currents
Explain how a change in one factor (like temperature) cascades through the whole ecosystem

Can your child explain why warmer ocean temperatures don't just affect one species — they change the whole ecosystem, from the plankton at the bottom of the food web to the whales at the top?
