What indirect food chain effect makes territories with high numbers of aphids valuable to the foraging Eurasian Wryneck?
Answer
Aphids support high aphid populations, which are a significant food source for many ant species
An interesting ecological correlation exists regarding favorable territories for the Eurasian Wryneck related to plant life. Favorable areas are often characterized by high numbers of aphids. This high value is indirect: aphids serve as a significant food source for many species of ants. Consequently, the presence of plants that support robust aphid populations leads to the establishment of strong, abundant ant colonies. This successful ant colony presence, in turn, makes that specific tract of land highly valuable and productive for a foraging Wryneck seeking its primary diet.
