scientists use models to them study systems in nature, such as predicting the paths of hurricanes, demonstrating how cell organelles work, or determining the effect building a dam would have on the local ecosystem. explain why models are used in science.

The scientific models are the visual representation of the complex natural systems. These models could be presented in the form of a diagram, 2 dimensional or 3-dimensional models which represent the simplified versions of the natural systems.  

The models are used by the scientific communities to explain the very complex phenomenon in simple terms to laymen.

They also play an important role in the research as they can be used to prove or disprove the hypothesis suggested by scientists.

The models act as a physical model to represent the very large and very small models like the solar system and the microscopic organism.

Thus, scientific models play an important role in the scientific world.
