Textbook Question
Textbook QuestionTwo endothermic animals are the same size, but one is a carnivore and the other is an herbivore. Predict which of these animals would produce the greatest amount of nitrogenous wastes. Explain.
Verified step by step guidance
1
Understand the metabolic processes of carnivores and herbivores. Carnivores primarily consume meat, which contains high levels of protein. Herbivores consume plant-based diets, which are generally lower in protein.
Recognize that protein metabolism in animals leads to the production of nitrogenous wastes such as urea or uric acid.
Consider the dietary intake of the two animals. Since the carnivore consumes a higher protein diet, it metabolizes more protein compared to the herbivore.
Relate the amount of protein metabolized to the production of nitrogenous wastes. More protein metabolism results in more nitrogenous waste production.
Conclude that the carnivore, which consumes a diet richer in proteins, would produce a greater amount of nitrogenous wastes compared to the herbivore.
