It helps nitrogen and hydrogen to react so as to produce ammonia (Haber process)Ammonia can be used as fertilizer. It helps the plants to grow faster as it provides the nitrogen which is an essential factor to plants' growth.
Biological catalyst- Amylase
Amylase is found in our saliva and is responsible for starting to break down the starch that we eat. So amylase is an enzyme that carries out the specific reaction of breaking down starch into a simple sugar.

Because silver is catalyzing a gas reaction, this is an example of heterogeneous catalysis.
