Question

The relationship between Yucca plant and Yucca moth is classified as:

Options

• Parasitism

• Facultative mutualism

• Obligate mutualism

• Commensalism

Answer 1

The Yucca-Yucca moth relationship is the classic example of obligate mutualism in biology. Neither organism can complete its life cycle without the other; the moth depends on the Yucca ovary for larval nutrition, while the plant depends on the moth for pollination and seed development.
