PLAAASE HELP The Gila woodpecker lives in the deserts of the southwestern United States. This bird eats insects that damage the saguaro, a common type of cactus. The bird pecks at the cactus to remove the insects. As it pecks, it removes damaged cactus tissue. It also makes a nesting cavity for itself. The nesting cavity does not negatively affect the saguaro. Any nesting cavity not being used by woodpeckers is available for use by lizards, rodents, and other birds. Name examples of predation, mutualism, and commensalism that involve the Gila woodpecker. a. Why would the Gila woodpecker be considered a keystone species in its ecosystem?
b. Name examples of predation, mutualism, and commensalism that involve the Gila woodpecker.
c. What is one way a desert ecosystem would be affected if climate change were to cause a decrease in the Gila woodpecker population?
