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?
(A) Lugworms have specialized taste receivers, which allow them to access nutrients below ground far more easily than earthworms can.
(B) The whooping crane, the earthworm’s chief predator, hunts along the mudflats during the time the earthworms are feeding at the surface.
(C ) Lugworms resemble the color of the mudflat, and are thus more difficult to spot by predators than earthworms are.
(D) Compared to the lugworm, earthworms are able to consume fewer nutrients at one time.
(E) Lugworms tends 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.
The mudflats of Garantia, contains two types of annelids - Lugworm and Earthworm.
Earth worm prefers regions with more moisture and nutrients , which is typically the surface of the mudflats. They emerge in the early mornings to absorb this nutrients. The access to nutrients enables the earthworm to reproduce and grow in larger quantities.
Compared to Earthworm, Lugworm remains dormant submerged inside the soil for much of the day. But, the Lugworm population remains relatively large compared to earthworms.
Among the options mentioned, which is the LEAST supporting answer for this paradoxical situation, let’s look into the options:
(A) Lugworms have specialized taste receivers, which allow them to access nutrients below ground far more easily than earthworms can.
Since, Lugworms are equipped specialized tatse receivers that access nutrients more easily , and hence they gather more nutrients, thereby reproducing more. This seems a possible explanation to resolve the paradox.
(B) The whooping crane, the earthworm’s chief predator, hunts along the mudflats during the time the earthworms are feeding at the surface.
Predators feeding on earthworms in large numbers during day time reduces the population in more numbers, so population of earthworms is less than Lugworms.
(C ) Lugworms resemble the color of the mudflat, and are thus more difficult to spot by predators than earthworms are.
This can also be one among the reasons why population of Lugworm is more than Earthworm.
(D) Compared to the lugworm, earthworms are able to consume fewer nutrients at one time.This Option is irrelevant, because consuming nutrients at one time doesn’t help us to reason out anything conclusive. May be the frequency of nutrient intake might be high, so that they have taken more nutirents.
(E) Lugworms tends 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.
This also can be seen as a reason for the thriving population of Lugworm compared to Earthworms.
