What is a type of standing water habitat in which the soil is acidic?

A type of standing water habitat with acidic soil is a bog. Bogs are typically characterized by their accumulation of peat, low nutrient levels, and the presence of sphagnum moss. These habitats often form in cooler climates and are home to specialized plant species adapted to the acidic conditions, such as carnivorous plants and certain orchids. Due to their unique ecology, bogs play a crucial role in carbon storage and biodiversity.
