The distribution of temperature, light, and nutrients set broad conditions for life in aquatic biomes in much the same way that climate and soils do for land biomes. Marine and freshwater biomes change daily or seasonally. For example, in the intertidal zone where Freshwater ecosystems are a subset of Earth's aquatic ecosystems.They include lakes and ponds, rivers, streams, springs, bogs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. Freshwater habitats can be classified by different factors, including temperature, light penetration, nutrients, and vegetation.
