Question

How are saprotrophs different from symbionts

Answer 1

saprotrophs feed upon microorganisms and bacteria for example Indian tube plant..

that means the feed upon non living organisms...

symbionts : lichen is a combination of fungi and algae this comes in symbionts in this both living organisms help each other fungi gives water and place for algae to make food and algae makes food and gives to fungi in this way both can survive this is known as symbionts..

Answer 2

All fungi are heterotrophic, which means that they get the energy they need to live from other organisms. Like animals, fungi extract the energy stored in the bonds of organic compounds such as sugar and protein from living or dead organisms. Many of these compounds can also be recycled for further use.

Fungi have evolved diverse strategies for obtaining organic (carbon-based) compounds, however. Broadly, fungi are either saprotrophs (saprobes), which decay dead organic matter, or symbionts, which obtain carbon from living organisms.
