Termites primarily consume cellulose, which is a key component of plant cell walls, making them critical for the ecosystem. Their ability to break down cellulose is vital as it allows them to recycle nutrients back into the soil. This process contributes to soil health and fertility, promoting plant growth and aiding in the overall functioning of ecosystems.

By digesting cellulose, termites help decompose wood and other plant materials, which not only cleans up organic matter but also creates a habitat for other organisms. This activity enhances nutrient cycling, making it accessible to a wide range of plants and contributing to the biodiversity of their habitats.

The other options, such as leaves, roots, and fruit, represent different plant components that may be consumed by various organisms but are not the primary food source for termites. Termites specifically target cellulose for their diet, which is why understanding their role in ecosystems is centered on this aspect of their biology.
