What role or reason do roaches play on earth?

Question

other that giving us the creeps.

Answer 1

Cockroaches are generally omnivores. An exception to this is the wood-eating Cryptocercus species found in Russia, China, Korea and the United States. Although they are incapable of digesting the cellulose themselves, they have a symbiotic relationship with a protozoan that digests the cellulose, allowing them to extract the nutrients. In this, they are similar to termites and current research suggests that the genus Cryptocercus is more closely related to termites than it is to other cockroaches. Cockroaches are most common in tropical and subtropical climates. Some species are in close association with human dwellings and widely found around garbage or in the kitchen

Roaches are all about eatting unwanted materials and recycling it into a usable source of energy for the planet.
