Which statement about biological legacies is true?

• A. The practices left to influence future regeneration
• B. The products marketed after harvest
• C. The stuff left after a disturbance
• D. The methods used for planting

Answer: (C)

Biological legacies are the living components and organic material that remain after a disturbance and help shape how the ecosystem recovers. This concept is captured by describing legacies as the stuff left behind when disturbance occurs, because those residual elements—like surviving trees, standing dead trees (snags), fallen logs, seeds still in the soil, root systems, and the soil’s microbial community—provide the seeds, nutrients, shelter, and relationships that drive regeneration and recovery. For example, seeds stored in the soil or in surviving trees can sprout after a disturbance, coarse woody debris can protect seedlings and create favorable microhabitats, and intact mycorrhizal networks can aid new plant growth. These legacies influence both the speed and trajectory of forest recovery. The other options refer to human actions or products, not the residual biological components that guide regeneration, so they don’t fit what biological legacies describe.
