How are amoeba unharmful?

Answer 1

Amoebas, particularly those found in freshwater environments, are generally harmless to humans and play a crucial role in the ecosystem by breaking down organic matter and serving as a food source for other organisms. Most amoebas are not pathogenic and do not cause disease; they thrive in their natural habitats without affecting humans adversely. However, some species, like Naegleria fowleri, can be harmful if they enter the body through the nose, but such occurrences are rare. Overall, the majority of amoebas contribute positively to their ecosystems and pose little threat to human health.
