Aphids are hemipterans that suck phloem liquid from plants. Ants are often seen collecting the liquid off the posterior end of the aphid and collecting the liquid that is released from the aphid's digestive system. In an effort to understand this interaction, several researchers measure the survival rates of aphid populations when ants were present and when they were excluded. Their results are shown. Which of the following conclusions is most consistent with the data? Select one: A. Ants protect the aphids from predators. B. Ants derive nourishment from the aphids. C. Ants parasitize the aphids. D. Ants carry the aphids to a food source.
Ground squirrels give an alarm call to warn others of the approach of a predator a. chemical communication b. auditory communication c. visual communication d. tactile communication
Aphids are small insects that feed on the sap of phloem vessels in plants and are destructive to crops and garden plants. In order to help control aphids naturally, farmers and gardeners will introduce ladybugs that eat aphids as their food source. What type of relationship exists between the aphid and the ladybug?
