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

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

•  The aphids and plants are an example of commensalism while the ladybugs and plants

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

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