Question

Each year, earthworms move deep into the soil during the fall and winter and return toward the surface in the spring and summer. What is the likely stimulus for this behavioral response? A. light B. soil pH C. rainfall D. temperature

Answer 1

Answer:

Explanation:Earthworms in winter, like earthworms during drought (dry soil conditions), burrow deeply. Night crawlers, the biggest of the garden worms (at least in my neck of the woods) will tunnel as much as six feet down, taking organic matter with them. There they build permanent burrows and wait for moisture.

All earthworms do more than just burrow to escape frozen ground. Once down as deep as they will go, they curl up tightly, surrounding themselves in insulating slime. In summer, during hot and dry spells, they enter a hibernation-like state known as estivation. In winter, the worms hibernate, waiting for soil to thaw before moving upward.
