What is saprophytism and neutralism?

Saprophytism is a type of ecological relationship where organisms, typically fungi and bacteria, obtain nutrients by decomposing dead organic matter, playing a crucial role in nutrient cycling. Neutralism, on the other hand, refers to an ecological interaction where two species coexist in the same environment without significantly affecting each other, meaning neither species benefits nor is harmed by the presence of the other. Both concepts illustrate different ways organisms interact within ecosystems.
