Plants on the shoreline of water bodies like ponds, lakes, rivers, etc. play a very important role.
These include roles like the prevention of soil erosion. The water is in constant motion and as waves strike the shore, they tend to loosen soil particles. Plants bind soil with their roots and this prevents it from falling into the water body, thereby ensuring that its depth is maintained.
Plants help in maintaining the quality of water and nourish it with nutrients for other organisms that live in the water. In the absence of plants, excess nutrients flow into the water leading to an imbalance that deprives animals like fish of essential nutrients and which can also lead to sudden bursts in the growth of algae and other microbes that are toxic to other organisms.
It is estimated that 90% of all aquatic life relies on the area where the land meets the water. A large number of animals are born here or spend a portion of their life cycle here. This area is also the source of food for a large percentage of marine organisms. The plants located on the shoreline are both part of the food chain in addition to providing a habitat where animals can seek shelter.
