Ant lions are small insects that dig funnel-shaped depressions in sandy areas. They hide in the dirt at the bottom of the funnel. When an ant climbs into the funnel, the ant lion feels the dirt shift and lunges out to grab the ant, shaking it death and then eating it. The relationship between the ants and ant lions is an example of

Predator-prey relationship

Explanation:

A predator prey relationship is one in which interactions usually with consequential effects occurs between two different species. One species usually feed on the other. The species being fed on are the prey while the species being fed is the predator. In this context, the prey is the ant and the predator s are the ant lions.

The relationship between the ants and ant lions is an example of predator-prey co-evolution.

Explanation:

Co-evolution refers to cases where two (or more) species reciprocally affect each other's evolution. Co-evolution is likely to happen when different species have close ecological interactions with one another. These ecological relationships include: predator/prey and parasite/host. The ecological relationship between pit-digging larval ant lions and their common prey, ants, is an example of how the specific ecological niche that species inhabit imposes selection pressures leading to specific behavioral adaptations. Ant lions rely on multiple strategies to capture prey with a minimal expenditure of energy and extraordinary efficiency while ants employ several different strategies for avoiding capture, including rescue of trapped nestmates.
