Saprophytic nutrition is important for:

Saprophytic nutrition is a type of nutrition where an organism feeds on dead or decaying organic matter. Saprophytic nutrition is important because it helps to decompose dead matter and recycle nutrients back into the ecosystem. This recycling of nutrients is vital for the growth and survival of living organisms. 

Without saprophytic organisms, the dead matter would accumulate and nutrients would become locked up, making them unavailable for use by other living organisms.
