What is the type of nutrition associated with saprophytic organisms?

Saprophytic nutrition is a type of heterotrophic nutrition where an organism feeds on dead or decaying organic matter. Heterotrophic nutrition is a mode of nutrition where an organism obtains organic molecules and nutrients from other organisms or from their environment. Heterotrophic organisms cannot produce their own organic molecules and therefore rely on other organisms or sources of organic matter for their survival.

Therefore, the correct answer is "Heterotrophic nutrition."
