Explain in detail the biotic and abiotic degradation of plastic.

Biotic and abiotic degradation of plastics are two processes through which plastics can break down, albeit at varying rates and efficiencies, in the environment.

### Biotic Degradation
Biotic degradation involves the breakdown of plastics by living organisms such as bacteria, fungi, and algae. These microorganisms use enzymes to degrade plastics into smaller molecules that can be assimilated as nutrients. Biodegradable plastics, such as polylactic acid (PLA) __________ _________ _______ ___ ________ _____ _______ ________ ____ ___.
