Answer the following Read the paragraph and answer the questions given below it. Food poisoning can occur due to contamination of food by various bacteria and fungi.Clostridia are bacteria responsible for spoilage of cooked food. There are around 100 species of this bacteria viz. Clostridium tetani, Clostridium botulinum, etc. that are present either free living in soil or the alimentary canal of humans and other animals. The bacteria are rod- shaped and produce pottle-shaped endospores in adverse environmental conditions. These microbes cannot withstand normal oxygen levels in air and grow under anaerobic conditions. How does Clostridium survive even under adverse conditions?
