Abstract
The nematode Caenorhabditis elegans (C.elegans) is capable of choosing a high quality food that best supports its growth. Nematodes were placed between two food sources, Bacillus megaterium (B.megaterium) and Escherichia coli (E.coli), on nematode growth agar. The number of nematodes in each food source was counted for 25 minutes at one-minute intervals. Greater numbers of C. elegans were found in E.coli than in B.megaterium. This suggests that E.coli is a higher quality food source than B.megaterium.
