Why are termites considered beneficial in the ecosystem?

Termites play a crucial role in ecosystems primarily through their ability to decompose dead wood and recycle nutrients. As social insects that feed on cellulose found in wood and plant material, termites break down this tough organic matter, which might otherwise accumulate and lead to a buildup of detritus in the environment. This decomposition process releases nutrients back into the soil, enriching it and supporting plant growth.

By facilitating the breakdown of plant materials, termites contribute to nutrient cycling, which is essential for maintaining the health of terrestrial ecosystems. The actions of termites not only support plant diversity and productivity but also create habitats for various microorganisms and other soil-dwelling organisms, enhancing soil structure and fertility.

While some of the other choices mention important ecological functions, none encapsulate the direct and critical role of termites in nutrient recycling and decomposition as effectively as the correct option does.
