  2. BThe relationship is facultative, meaning both the moth and the plant can complete their life cycles independen
  3. CThe moth larvae feed on the pollen grains of the flower as they develop.
  4. DThe moth deposits its eggs in the locule of the ovary and the flower gets pollinated by the moth.

Correct answer

D. The moth deposits its eggs in the locule of the ovary and the flower gets pollinated by the moth.

Step-by-step solution

In the mutualistic relationship between the Yucca plant and the moth, both species are obligately dependent on each other and cannot complete their life cycles independently. The moth deposits its eggs in the locule of the ovary (not the mature fruit), and in turn, the flower gets pollinated by the moth. The larvae of the moth come out of the eggs and feed on the developing seeds, not the pollen grains. Answer: The moth deposits its eggs in the locule of the ovary and the flower gets pollinated by the moth.
