The role of crustaceans in nature and significance for humans.

Crustaceans play an important role in nature, as do most species. They are involved in water filtration. You also need to remember that crustaceans are in many food chains. Without these animals, some chains will be broken. Some species will become smaller, while others, on the contrary, will become larger. Man uses crustaceans mainly in the food industry. They are harvested from their natural habitat or bred on special farms. It is also worth remembering that crustaceans are involved in the formation of various breeds.
