Termites cut wood with the help of enzyme produced by
Correct answer: C. Trichonympha
- A. Trichonella
- B. Tripanosoma
- C. Trichonympha
- D. Trichina
Explanation
Although termites are insects that eat wood, they are not capable of digesting wood on their own. Endosymbionts that live within the intestines of the termite assist in converting the wood into nutrients that the termite can digest. One of the several types of endosymbionts that live inside the termite is single-celled organisms called Trichonympha (protozoa). Trichonympha has the enzymes needed to convert cellulose in wood into starches and sugars that the termite can use as nutrients.
