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 that 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

Abundant light is necessary for photosynthesis by the zoochlorellae, but without a source of nutrients (such as bacterial prey), the zoochlorellae will not be able to reproduce and colonize the P. bursaria cell. Therefore, the combination of abundant light and abundant bacterial prey would be most favorable for the reestablishment of resident zoochlorellae.
