Answer:
The marshes are defined as the type of wetland where the water covers the ground surface for a long period of time. Here, the trees are absent and are mostly dominated by the grasses and other small herbivore plants. They are commonly formed in delta type of environment where the rivers adds water into the seas. It forms an isolated and distinct ecosystem.
The marshes in nature, behaves like a filtration process as the vegetation that are present in marshes takes up more amount of nutrients for their growth and expansion. But, if it does not use up these excess nutrients then it cause water pollution comprising of nitrogen and phosphorous.
They also plays an important role in the reduction of damages that are caused by a flood.
The marshes are sometimes seasonal and it occurs when the height of the river level is relatively high, and it floods the grassland areas.
The marshes are of three types-
(1) Tidal salt marshes
(2) Tidal freshwater marshes
(3) Inland freshwater marshes.
The moisture is the same throughout the air mass.
1) prevailing westerly winds
2)the North Atlantic Drift ocean current
ႊ့These two moderates much of the air temperature over Northwestern Europe.
Hope this helps!
Answer:
Option (D)
Explanation:
Organic detritus usually refers to those materials that are the remains of dead organisms such as plants and animals.
The flowing water ecosystem such as the head-water streams obtains most of the materials from the nearby terrestrial and aquatic places due to the surface runoff. It is highly rich in the amount of organic detritus, as the materials such as leaves, branches, roots, soil particles, and other organic waste products are transported from the land areas, thereby obtains its energy from them.
Thus, the correct answer is option (D).
