Mealy bugs are small insects that live on various types of plants and feed on their sap. When there is a large population of mealy bugs occupying a plant, they may remove too much sap causing the plant to change color or wilt. Ladybugs eat mealy bugs and are often used in greenhouses to control the population. Which type of relationship exists between the mealybugs’ ladybugs and plants?

• The relationship between the ladybugs and mealybugs are an example of competition.

• The ladybugs and mealybugs are an example of predation while the mealybugs and plants are an example of parasitism.

• The ladybugs and plants are an example of mutualism while the mealybugs and plants are an example of parasitism.

• The mealybugs and plants are an example of commensalism while the ladybugs and plants are an example of predation.
