What is the foodchain of a rockpool creature?

Answer 1

That thing eats Humans.

Answer 2

In a rockpool ecosystem, a common food chain might involve algae at the base, followed by herbivorous creatures like snails or small fish that feed on the algae. These herbivores may then be consumed by predators like crabs or seabirds. Ultimately, decomposers like bacteria or fungi break down the waste and dead organisms, returning nutrients to the ecosystem.
