Final answer:
An analytical model is considered more ecologically realistic for biological systems. Computer simulation models can be accurate without observations or experiments on actual living organisms or tissues, but they should be validated through comparisons with real-world data. Both physical models and computer-based models should be built around a hypothesis and test that hypothesis.
Step-by-step explanation:
An analytical model is considered more ecologically realistic for biological systems. While computer simulation models can be accurate without observations or experiments on actual living organisms or tissues, they still need to be validated through comparisons with real-world data. Both physical models and computer-based models should be built around a hypothesis and test that hypothesis.
