What can you infer about the needs of ferns from the fact that they thrive on the floors of thick forests?

Ferns thrive on the forest floor, indicating they prefer shaded environments with high humidity and consistent moisture. These conditions suggest that ferns have adapted to low light levels, relying on the filtered sunlight that penetrates the canopy. Additionally, their presence in thick forests implies a need for rich, organic soil, which provides essential nutrients for growth. Overall, ferns require a stable, moist habitat to flourish, highlighting their ecological role in forest ecosystems.
