Which is a major benefit of the natural recycling of biodegradable materials? a) the materials increase the load on landfills. b) the materials decompose and enrich the soil. c) the materials reduce the need for recycling programs. d) the materials can be used to make new products.

I believe the answer is: B) The materials decompose and enrich the soil.

Biodegradable material is made with materials that could be broken down by microorganism (such as fruits and vegetables)

This would become the source of nutrients for the plants that grow near the soil and actually give positive contribution for the environment.
