Wood Destroying Organism (WDO) Home Inspection Practice Exam

What do termites primarily use to advance through the wood they consume?

1. A) Saliva

2. B) Acids

3. C) Pheromones

4. D) Enzymes

The correct answer is: D) Enzymes

Termites primarily use enzymes to break down the cellulose in wood, which is their main food source. These enzymes are produced in their guts, particularly the protozoa that coexist in their digestive system. Cellulose, a complex carbohydrate that forms the structural component of plant cell walls, is difficult to digest, but termites have developed a symbiotic relationship with these microorganisms that allows them to effectively decompose the cellulose into simpler sugars that they can absorb and use for energy. The role of enzymes in this process is crucial, as they catalyze the chemical reactions necessary to break down the cellulose chains into digestible units. This enzymatic activity is a key factor in the termites' ability to thrive in their environment by efficiently consuming wood. Understanding this digestive process is important for assessing the extent of termite damage and understanding their biology in the context of wood-destroying organisms.
