There are several different kinds of aquatic ecosystems. Bogs get their water from precipitation, so they don't have many Fill i
Ratling [72]
  1. Bogs get their water from precipitation, so they don't have many <u>nutrients</u>.
  2. Marsh plants are adapted to waterlogged <u>soil</u>
  3. Swamps have <u>plants like trees and shrubs</u>.
  4. Rivers always have flowing currents and pick up <u>sediment</u> as they flow.
  5. Lakes are bodies of water on land.  
  6. Wetlands act as filters for nutrients and pollutants dissolved in the water.
  7. Estuaries are wetland regions where freshwater rivers mix with ocean water.

Explanation:

A wetland is a biome which has both water and land that are intermixed in various ways. According to the type of the wetland, the ecosystem differs.

Bogs: Wetland with water from precipitation and no inflow or outflow of surface or ground water.  

Soil: Acidic, infertile with less nutrient content

Vegetation: Acid-loving plants

Swamps: Forest wetlands near rivers and lakes.

Soil: well draining, mineral soil

Vegetation: Trees and bushes. Swamps are classified according to the vegetation, like coniferous swamp, hardwood swamp, shrub swamp etc

Marsh: Wetlands mostly inundated with water leading to waterlogged soil  

Soil: Organic and mineral soil

Vegetation: Hydrophytic plants adapted to waterlogged soil

Estuaries: Wetland regions enclosed by land one side where fresh water mixes with saline ocean water.  

Soil: Saline alkaline soil

Vegetation: Mangrove trees

Rivers and lakes are water bodies that form a part of wetlands.  

Rivers are flowing water bodies which flows through water current and picks up sediments as it flows.

Lakes are stationary water bodies that are enclosed by land mass on all its sides.

The wetlands act as a natural filter and receive all the sediments, pollutants etc which are dissolved in water and carried by the rivers and other water sources.

What discovery could provide evidence against the theory of evolution?
Viefleur [7K]
A discovery that could provide evidence Against the theory of evolution is: If a primate and a trilobite fossil were found in the same rock layer. Because if that were to happen, then that means that trilobites and primates were from the same time frame, and it also means that primates did not evolve that they were the same since they first lived on the earth.

Coking coal is a type of Bituminous coal are best used as fuel dource in metal industry having very narrow range of volatility and plasticity. Volatility is maintained by smelters  to optimize the ease of burn rate,  ignition, and energy output of the coal as this determines the burn rate of the coal.

Hence, the correct option is B. bituminous.
