Most freshwater hydrozoa exist only as the polyp form. They never switch to the medusa form, or sexual form. This means they exist only in the asexual form.
There are no freshwater oceans. Only where large rivers empty into the sea, there are some areas of lower salinity, but no freshwater oceans.
Wetlands are wet because they exist only near the ocean and usually flood and drain during high and low tide. Wetlands coexist with the ocean to make a fragile and abundant ecosystem, and subsequently are wet most of the time.
No other organisms compete with the platypus for food. Its feeding habits and its habitat are unique. No other mammal feeds on the variety of freshwater crustaceans and other invertebrates for which the platypus forages. In wetland areas, only freshwater wading birds have a similar diet, but the platypus prefers clear rivers, lakes and creeks rather than wetlands for its habitat.
By "in America", that would mean Canada, United States, and South America. If you mean only in the US, there are vast areas of swamps in the south-eastern States. But as well, wetlands exist in many States across the US. They would be too numerous to count.
no
neither, the ecosystem 'wetlands' is not a producer or a consumer. but plants and animals inside the wetlands are consumers and producers. Keep this in mind, only plants are consumers. Also be specific which wetlands you are talking about in the world
The weather in a wetlands is determined by geography and climate. Only larger wetlands have an effect on their environment. As water evaporates from the wetlands, it can create humidity and more frequent rain.
The freshwater biome covers only 0.8% of the total water on this Earth, yet the water which makes up this biome are distributed unevenly throughout the globe. As a result the climate of these Biomes is greatly diverse depending on the region.
Yes. Platypuses can only live in freshwater ecosystems.
Melting is the only threat to the freshwater ice sheet.
The question needs to be refined, as there are hundreds of freshwater fish species.
