The correct answer is "are homes to unique plants and animals".

Explanation:

Estuaries are areas of water that provide environmental and chemical characteristics that are unique because of their location where rivers meet the ocean or another large bodies of water. Estuaries are homes to unique plants and animals that have adapted to variations in water salinity as well as the fall and down of tides.
