Nematodes are the most abundant metazoan organism on the planet with on average

Question

Nematodes are the most abundant metazoan organism on the planet with on average several million individuals m-2 . Reproduction is direct with female worms producing a varying number of eggs based on species. An estuarine population of Monhystera denticulata studied in culture had an initial, total population size of 1,780,822 with males being 27% of the total. Female M. denticulata produce on average 15 eggs with the average generation time being 18 days.

Based on the information above and extensive knowledge of nematode population biology (e.g., overlapping generations) one could conclude that, in the absence of any limiting resource in culture, the M. denticulata population would _____________________.

(a) grow exponentially

(b) have discrete, non-overlapping generations

(c) achieve a maximum growth rate at ½ of the population carrying capacity

(d) exhibit geometric population growth

Explanation / Answer

In the absence of any limiting resource in culture, the M. denticulata population would achieve a maximum growth rate at ½ of the population carrying capacity because if there will not be any limiting resource in culture the M. denticulata population will decrease as mentioned above that if an estuarine population of Monhystera denticulata had an initial, total population size of 1,780,822 with males being 27% of the total in this case female lenticulata produce on an average 15 eggs with the average generation time being 18 days this is for the case when overlapping generations are there.
