Question

Distinguish between a parasite and a saprotroph.

Answer 1

Hint: Organisms which depend on others for survival and get required nutrition.

Complete answer:

Parasite	Saprotroph
An organism that develops and absorbs nutrients from another organism's body.	An organism that obtains nutrients from organic matter is dead and rotting.
They take from the host the ready-made food.	The digested and decayed food is taken from them.
They feed on living organisms directly for their nutrition.	They feed on an organism that is dead and rotting.
Many bacteria, living within the organism, are parasitic, consuming digested food from it.	Digestion is external, and the body consumes the digested food.
They harm the host's body.	They are washing agents.
The plant in Cuscuta is a parasite.	Saprotroph is a fungus.

Additional information:
 Parasites are organisms that grow/inhabit the host's body and extract nutrients from them. As a consequence, they are supplied with ready-made food from the body of the host and have the ability to cause significant harm to the host as they rely directly on them. Parasites can not survive and grow without a host. Therefore, they do not kill the host but can cause diseases that cause damage, few of which can be fatal. Parasites are much smaller than their hosts as they quickly multiply, unlike predators.

Saprotrophs are living organisms that derive their nutrition from organic matter that is dead and rotting. A host is not needed by Saprothrophs. They are also described as cleaning agents because they derive nutrition from dead matter

Note:A relationship between two species, a parasite and its host, in which the parasite profits while the host is harmed, is characterised by parasitism. Parasitism is one type of symbiosis that defines, more broadly, any situation involving a close relationship between different species of organisms.
