Along the mudflats of Garantia exist two types of annelids: earthworms and lugworms. Earthworms tend to emerge from the mud early in the morning when there is more moisture and nutrients. As a result, earthworms have access to more nutrients and thus reproduce far faster than the lugworm, which spends much of the day submerged in the mud. Nonetheless, the lugworm population far outnumbers that of the earthworm.

Which of the following, if true, helps LEAST to resolve the apparent discrepancy noted above?

【选项】Lugworms tend to emerge in the evening, when the number of predators is less than during the early morning hours, when the earthworm is exposed on the mudflat.
