Final answer:
In Taiben's forest walk, a fish swimming involves both biotic and abiotic components, whereas a fox catching a rabbit involves only biotic components.
Step-by-step explanation:
Taiben's observation of a fish swimming in a creek is an action that has both biotic and abiotic components involved. The fish (biotic factor) interacts with the water in the creek (abiotic factor) as it swims. On the other hand, the action of a fox catching a rabbit involves only biotic components, as both the fox and the rabbit are living organisms.
An action that involves only biotic components is the predation. In this case, the fox catching the rabbit is an example of predation, where one organism (the predator) feeds on another organism (the prey) for energy.
