Sample QuestionTermites are small insects that eat wood causing so much damage that they can eventually cause a house to fall down. However, termites cannot make enzymes that digest cellulose, the main component in wood. A small protozoan called Trichonympha sphaerica lives inside the termite’s gut and excretes enzymes to break down cellulose. However, the protozoa itself cannot make the enzymes. Instead, a species of bacteria that lives inside the protozoa produces the enzyme. What type of relationships are described in this passage? (Standards 6.1f, 6.1g, 6.3a)
