Answer:
In nature, there are a number of useful soil micro organisms which can help plants to absorb nutrients. Their utility can be enhanced with human intervention by selecting efficient organisms, culturing them and adding them to soils directly or through seeds. The cultured micro organisms packed in some carrier material for easy application in the field are called bio-fertilisers. Thus, the critical input in Biofertilisers is the micro organisms.
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.
