  1. Probiotics are made of both bacteria and yeast: This statement is correct. Probiotics are live microorganisms that are intended to have health benefits when consumed or applied to the body. They are made up of various strains of bacteria, as well as yeast and other microorganisms.

  2. Probiotics help in the digestion of milk sugars: This statement is also correct. Some probiotics, particularly those in the Lactobacillus and Bifidobacterium families, are able to break down lactose, the sugar found in milk. This can be beneficial for people who are lactose intolerant and have difficulty digesting dairy products.

Statement 2, on the other hand, is incorrect. Probiotic organisms are not just found in the foods we eat, but also occur naturally in our gut microbiota. In fact, some of the most well-known probiotic strains, such as Lactobacillus and Bifidobacterium, are part of the normal human gut microbiota. Therefore, statement 2 is false.
