Explore the Ecosystem: Test Your Knowledge
Welcome to the "Explore the Ecosystem" quiz! This engaging quiz covers a wide range of topics related to ecosystems, biomes, and aquatic organisms. Designed for learners of all levels, it will challenge your understanding of the complex interactions between living organisms and their environments.
Test your knowledge on:

- Energy flow and trophic levels
- Categories of aquatic organisms
- Freshwater zones and their productivity
