Question

Why do scientists use models, and why do all models have limitations???

Answer 1

Answer:

Since models are simpler than real objects or systems, they have limitations. ... It may not predict the behavior of the real system very accurately. But the more computing power that goes into the model and the care with which the scientists construct the model can increase the chances that a model will be accurate.

Answer 2

Answer:

Scientists use  models to represent data/evidence. However, all models have limitations. However, models are simplified versions of reality, and can't be totally accurate in representation.

Hope this helps :)
