A healthy aquatic ecosystem includes producers like algae and phytoplankton, consumers like zooplankton and fish, and decomposers like bacteria. Specific biotic categories include:
- Plants
- Animals
- Fungi

Specific abiotic factor examples and how they may affect the biotic portions of the ecosystem include:
