aquatic substrate

Aquatic substrate refers to the material that makes up the bottom of lakes, rivers, and other bodies of water. This can include sand, gravel, mud, or rocks. Substrates play a vital role in aquatic ecosystems by providing habitat for various organisms, influencing water quality, and affecting plant growth. Different types of substrates support different types of life; for instance, some fish prefer rocky bottoms, while others thrive in sandy environments. Overall, the substrate is essential for the balance and health of aquatic ecosystems, serving as a foundation for many interactions among species.
