A P. bursaria cell that has lost its zoochlorellae is said to be aposymbiotic. It might be able to replenish its contingent of zoochlorellae by ingesting them without subsequently digesting them. Which of the following situations would be most favorable to the reestablishment of resident zoochlorellae, assuming compatible Chlorella are present in P. bursaria's habitat?
a. abundant light, no bacterial prey
b. abundant light, abundant bacterial prey
c. no light, no bacterial prey
d. no light, abundant bacterial prey

Aposymbiotic may be defined as the type of biological interaction in which the organism lives in association with each other but lives apart from one another.

P. bursaria's requires the light for their growth and metabolism. The prey acts as the food source for the P. bursaria's. Hence, abundant amount of the prey and the abundant amount of light is favorable for the growth of the organism P. bursaria's.

Thus, the correct answer is option (b).
