Snails and slugs chew and feed on algae, decaying organic matter, and various living plants. 

Snails and slugs feed using a technique known as "razor feeding." Instead of chewing, they scrape food from surfaces with a specialized structure called a radula, which is located in the mouth. 

They use the radula's tiny, sharp teeth to scrape algae, decaying plant material, and other organic matter from rocks, plants, and other surfaces. 

Snails and slugs are herbivores that consume a wide range of living plants, as well as algae and other plant-based materials. 

Some species have been observed feeding on fungi, lichens, and other types of decaying organic matter.
