Supernovae are important for creating the heavier elements.

Explanation:

The majority of matter in the universe is hydrogen and secondly helium.

Most stars convert hydrogen into helium by nuclear fusion.

More massive stars use the Carbon-Nitrogen-Oxygen fusion process to convert hydrogen into helium.

In order to produce the more heavy elements a lot more energy is required and supernovae provide the energy to do this. The fusion process liberates energy until the nucleus is iron/nickel after this fusion requires more energy to create nuclei than is released.

Supernovae have the energy to produce the heavier elements using processes such as neutron capture.
