what do you mean by symbiosis and saprotrophs
Answers
A symbiotic relationship means a mutually interdependent relationship. Two different kinds of organisms live together for their mutual benefit. For example, algae, which is an autotroph, and fungus, which is a saprophyte, live together in lichen.
Symbiosis-:
It is the interdependent of two organism on each other to survive. For example: In lichen plant the algae and fungi together live and show symbiosis by giving benefit to each other.(Algae are green thus they have Chlorophyll so they have the ability to prepare food so they are given nutrients from soil by fungus and in turn algae gives food to fungus to survive)
Saprotrophic mode of nutrition:-
In saprotrophic mode of nutrition the organism feed on dead and decaying matter of plants and animals for food. They follow external digestion means they secreate certain enzymes on the food which digests it and then they take in the food for utilisation. For ex. fungi, mushroom, yeast,
