To determine the relationship between the crow and the rat, we need to analyze their interaction based on the information given. In this scenario, the rat is trying to get food from the garbage can, but it is chased away by the crow. The crow ends up eating the food, forcing the rat to find other sources of food.
Therefore, based on this information, it is evident that the crow is preying on the rat, as it interferes with the rat's ability to obtain food. Consequently, the rat is the prey and the crow is the predator.
So, the correct answer is: b) The relationship is predator-prey.
