Answer:

b. False

Explanation:

<em>Caenorhabditis elegans</em> is a well-known species which is widely used in genetic experiments (i.e., it is a model organism). <em>C. elegans</em> is a soil nematode that eats bacteria, but its survival depends on the ability to distinguish toxic from non-toxic ones. <em>C. elegans</em> cannot feed <em>Bacillus thuringiensis</em> because this bacterium produces a toxin Bt protein that damages its gut, thereby producing the death of this nematode. Interestingly, it has been proposed that Bt toxin pathways might be exploited for the design of new generation nematicides.
