Question

Within the light organ, bacteria are protected and nourished, and rapidly increase in number. At night, they provide the light needed for counterillumination. But by dawn, as the squid prepares to hide in the sand for the day, it ejects about 95% of the bacteria from the light organ. Which of the following is the LEAST likely explanation for why eliminating 95% of the bacteria present in the light organ is necessary?

Answer 1

At dawn the squid prepares to hide in the sand for the day and it ejects about 95% of the bacteria from the light organ in order to reduce or stop the growth of bacteria population in the squid. This will prevent the bacteria population from reaching a level too high for the squid to support.
