   Concept:

   • Saprophyte – 
     • Any organism that survives or feeds on dead and decaying organic matter.
     • They convert complex organic compounds of a decomposing body into simpler ones.
     • This helps in the process of decomposition.
     • They are mostly fungi and bacteria.
   • Parasite – 
     • Organisms that attack living organisms rendering them weak.
     • Parasites live off other organisms called hosts, harming them and sometimes causing death.
     • Parasites live in or on the host and get their food from the host.
   • Lichens – 
     • A close symbiotic association between algae and fungi.
     • The fungi provide shelter and protection to algae and the algae provide photosynthetic products to the fungi.
     • Lichens only grow in pollution-free environments and hence are used to detect pollution.
   • Mycorrhiza – 
     • Symbiotic association between the plant roots and fungi.
     • Fungi absorb nutrients from the soil and provide them to the plant.
     • Plants in turn provide fungi with photosynthetic products.

   Key Points

   The correct match is as follows:

   A.	Saprophyte	2.	Decomposition of dead organic materials
   B.	Parasite	3.	Living on living plants or animals
   C.	Lichens	4.	Symbiotic association of algae and fungi
   D.	Mycorrhiza	1.	Symbiotic association of fungi with plant roots

   So, option (1) is the correct answer.
