If a field of green plants produced 1000 kg of biomass and a cow was allowed to eat all of the green plants, how much of the available biomass was actually transferred to the cow?

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

not only is it colder, it also becomes darker, less salty, and more dense.
