Ap. 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

Abundant light, abundant bacterial prey

Explanation:

A zoochlorella is a small green alga sometimes flagellated protozoa that lives within the bodies of various freshwater protozoans or marine invertebrates.

The condition that is favorable for the reestablishment of resident zoochlorellae is abundant light and abundant amount of bacterial prey.

This is because it lives in the body of the freshwater protozoans. Hence, the correct answer is option A    

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
