In a food web, primary consumers are organisms that eat primary producers (usually plants or phytoplankton). Among the options you provided, the primary consumers are:

1. **mayfly** - This organism primarily feeds on phytoplankton or other plant material.
2. **frog** - Frogs can be considered primary consumers when they feed on insects, but they can also be secondary consumers depending on their diet (e.g., if they eat other animals).
3. **salamander** - Similar to frogs, they mainly consume insects and other small creatures and can act as primary consumers when feeding on them.

Phytoplankton is a primary producer, while the other organisms listed (trout, human, bald eagle, dragonfly, snake) are typically secondary or tertiary consumers in the food web.

Thus, the primary consumers in your list are:
- mayfly
- frog
- salamander

Note: While frogs and salamanders can sometimes occupy multiple trophic levels, for the purpose of this question, we are identifying their roles as primary consumers.
