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
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
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?

This concept
Check understanding
- 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
