Explanation:

Predation, Food Chain,

The question is not very clear, but the word that best describes this activity is "predation" and "competition"

This is an example of predation because the frog is catching the fly and eating it, and is the predator in this interaction. it's an example of the food chain because the frog is higher up on the food chain than the fly.
