Answer

Brief Explanations:

In a food chain, primary consumers are herbivores that eat producers (autotrophs like plants/algae). Green algae are the producers here. Freshwater snails eat the green algae, so they are the primary consumers. Small fish eat snails (secondary consumers), large fish eat small fish (tertiary consumers).

Answer:

freshwater snails
