Final answer:
Boggy ground is an area of wet, spongy earth with poor drainage, often forming a bog or marsh, which is difficult to traverse and features a unique ecosystem with specially adapted plants.
Step-by-step explanation:
The term boggy ground refers to an area of soft, wet, and unstable earth, which is saturated with water and may have poor drainage. This type of ground is usually found in low-lying areas where water collects, forming a bog or marsh. Bogs are characterized by stagnant water, which is low in oxygen due to the slow decomposition of organic matter, and often have a clay bottom that impedes water percolation.
This condition can make traversing the land difficult, as vehicles and individuals may get stuck in the mud and movement becomes hindered. Such terrains also have a unique ecosystem, with plants like sundews, pitcher plants, and Venus flytraps that have adapted to extract nitrogen from insects due to the low levels of nitrogen and oxygen in the water.
