Question

a frog eats a fly. the frog and fly are demonstrating ____________. competition mutualism predator/prey parasitism

Explanation:

In this interaction, the frog is the predator (the one doing the eating) and the fly is the prey (the one being eaten). Predator - prey relationships are a fundamental concept in ecology where one organism (predator) hunts, kills, and consumes another organism (prey) for food. Competition is when two or more organisms vie for the same limited resource (like food, space). Mutualism is a symbiotic relationship where both organisms benefit. Parasitism is a relationship where one organism (parasite) benefits at the expense of the other (host), but the parasite usually does not immediately kill the host as in the case of a predator - prey relationship.

Answer:

predator/prey
