Which of the following is a key factor in termite life cycles?

Moisture availability is indeed a key factor in termite life cycles because termites require a humid environment to thrive. The presence of moisture in the environment is crucial for several reasons. It aids in the digestion of cellulose, the primary component of their diet, which comes from wood and plant materials. Termites rely on symbiotic microorganisms in their guts to break down cellulose, and these microorganisms flourish in moist conditions.

Additionally, moisture impacts the construction of termite mounds or nests, which are designed to maintain humidity levels that are essential to the survival of the colony. Without sufficient moisture, termites may struggle to survive, reproduce, and maintain their colonies, leading to a reduced population and impaired functioning of the ecosystem they inhabit.

Thermal regulation, symbiotic relationships with plants, and cold temperatures do play roles in termite life cycles, but they are not as directly impactful as moisture availability. While certain temperatures can influence termite activity levels, moisture remains the fundamental element that supports their life cycle processes.
