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.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
