Wetlands must have one or more of the following three attributes: 1) at least periodically, the land supports predominantly hydrophytes; 2) the substrate is predominantly undrained hydric soil; and 3) the substrate is saturated with water or covered by shallow water at some time during the growing season of each year.

Mangrove forests are tropical and subtropical ecosystem characterized by the presence of plant species adapted to high temperatures and organic matter content, and fluctuating salinities and oxygen conditions. Mangroves provide ecosystem services of great social, economic and environmental importance.

Freshwater biomes have less than 1% salt and are typical of ponds and lakes, streams and rivers, and wetlands. Marine biomes have more salt and are characteristic of the oceans, coral reefs, and estuaries. Most aquatic organisms do not have to deal with extremes of temperature or moisture.

Answer and Explanation: The characteristics of high biodiversity are that there are many different species in high abundance and the ecosystem is stable.

Four Types of Freshwater Wetlands. There are 4 main types of Freshwater Wetlands in North America; Ponds, Marshes, Swamps, and Peat bogs. A Marsh is usually found near a river, lake or tidal waters.

These properties can be physical, chemical or biological factors. Physical properties of water quality include temperature and turbidity. Chemical characteristics involve parameters such as pH and dissolved oxygen. Biological indicators of water quality include algae and phytoplankton.

Where wetlands have healthy biodiversity, they provide essential services to the environment and to our communities – providing and purifying water, acting as spawning and nursery grounds for fish, providing a refuge for animals in times of drought and providing recreational, cultural and, in some cases, spiritual ...

Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish, or saltwater. The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, mire, vernal pool, sink, and many others. Many peatlands are wetlands.

Marshes, swamps, and bogs are all considered wetlands. ... Wetlands are not considered freshwater ecosystems as there are some, such as salt marshes, that have high salt concentrations—these support different species of animals, such as shrimp, shellfish, and various grasses.

Freshwater biomes are subdivided into three groups: lakes and ponds, streams and rivers, and wetlands. There are four key features that determine the ecology of streams and rivers - the flow of the water, amount of light, the temperature or climate, and the chemistry of the river.

Florida wetlands generally include swamps, marshes, bayheads, bogs, cypress domes and strands, sloughs, wet prairies, riverine swamps and marshes, hydric seepage slopes, tidal marshes, mangrove swamps and other similar areas.

Some of the major amphibian characteristics that the frog exhibits is that it can breathe through its skin and lungs. Frogs also have webbed feet which is common of most amphibians. Frogs must live in moist environments to sustain life.
