Which is not a benefit of maintaining sustainable forest ecosystems? Select one:
O a. Empty space on which to build homes
b. Habitat for thousands of species
c. Reduction of erosion in watersheds

The correct answer as to which is not a benefit of maintaining sustainable forest ecosystems would be empty spaces on which to build homes.

An ecosystem refers to a network of communities interacting together as a unit. A forest ecosystem, therefore, is a community of different plants, animals, and microbes interacting together and with their physical environment as a unit.Sustainable forest ecosystem is a system of managing forest resources in such a way that the ecological processes and functions provided by the forest do not depreciate. The ecological functions of forest ecosystems include the provision of foods, drugs, and raw materials for man, protection of watersheds,  provision of habitats for other species, and playing important roles in the stability of climates.

Hence, not maintaining forest ecosystems in a sustainable way means that some of the functions they perform such as the provision of habitats for species and reduction of erosion in watersheds would be lost.

The only option that is not a benefit of maintaining sustainable forest ecosystems is A.
