Photorhabdus luminescens and the microscopic wormHeterohabditis bacteriophora are______(select one: nematode worms/wax worms/symbionts/bacteria). TheP. luminescens_____ (select one: nematode worms/wax worms/bacterium). lives in a ______(select one: nematode worms/wax worms/bacterial) host. This host then parasitizes an insect larva, and the ______(select one: nematode worms/wax worms/bacteria) within it produce _____(select one: spores/bacteria/toxins) that kill the _______(select one: nematode worm/wax worm/bacterium).

6. The relationship exhibited by P. luminescent bacteria and the nematode worm Heterorhabditis bacteriophora is a good example of ________. a.parasitism

b.mutualism

c.commensalism

Answer 1

5. Photorhabdus luminescens is perhaps the most unusual microbe yet proposed to be used as a bioinsecticide. Photorhabdus luminescens and the microscopic worm Heterohabditis bacteriophora are symbionts. TheP. luminescens bacterium lives in a nematode worms host. This host then parasitizes an insect larva, and the bacteria within it produce toxins that kills the wax worm.

The relationship exhibited by P. luminescent bacteria and the nematode worm Heterorhabditis bacteriophora is a good example of mutualism.
