About the framework
Follow the displayed marine feeding sequence
The sample runs from Sun to Phytoplankton, Zooplankton, Small Fish, Tuna / Mackerel, Sharks, and Orca (Apex). Bacteria / Decomposers appears below the chain, with a nutrients connection from the orca and a recycle connection back to phytoplankton.
Eight nodes and eight arrows form the example. The labels combine broad animal groups into one illustrative sequence; no location, species list, population data, or energy-transfer percentages are provided. Use it to inspect the structure of a chain rather than assume every link applies across the ocean.
For a lesson, name the marine habitat and replace the grouped labels with the organisms in your materials. You can shorten the sequence for younger learners or add feeding links to develop a food web.
What's included
What you get
- Eight nodes from Sun through Bacteria / Decomposers
- Phytoplankton and zooplankton at the start of the feeding sequence
- Small fish, tuna/mackerel, sharks, and an orca in order
- Separate energy, nutrients, and recycle labels on selected arrows

Frequently asked questions
Common questions
Does this represent a particular ocean habitat?
No. The example uses broad groups such as Small Fish and Sharks without a location. Supply a habitat and supported feeding links for a more specific version.
Are energy-transfer percentages included?
No. The Sun-to-Phytoplankton arrow is labeled energy, but the diagram contains no transfer efficiencies or biomass quantities.
How can I turn this chain into a food web?
Provide additional prey and predators for the chosen habitat, then ask to add multiple feeding connections while retaining a clear arrow direction.
