Human beings have an impact on river ecosystems. A forest ecosystem may be as small as a tree branch microsite where mosses, insects, and microscopic organisms interact or as large as the boreal forest that encircles the Earth at northern latitudes. River ecosystems (riverscapes) encompass ecological, social, and economic processes (ecosystem functions) that interconnect organisms (ecosystem structure), including humans, over some time period. The ecosystems in rivers and streams, for example, bring salts and nutrients from the mountains to lakes, ponds, and wetlands at lower elevations, and eventually they bring those nutrients to the ocean. %PDF-1.1 ADVERTISEMENTS: Pond and lake are fresh water ecosystems in which, like other ecosystems, there are two main components: (A) Abiotic component (B) Biotic component ADVERTISEMENTS: (A) Abiotic component: Abiotic component of pond consists of water, dissolved minerals, oxygen and carbon dioxide. }�N)��4 �5�P8$ �BaP�R�DbPhtN-�5ⱘ�v�+ �)#^E���x�FA�J�b�VV����Y²s2�L�3ؔ�O ��i-y��m:������uU�Dh�y��M,�R�� ��>�YP3x=.W�ɠTiDb�e���w�e��e�Zfw뽂!

This is known as a lotic (flowing water) system. Ecosystems have no particular size. In fast moving waters animals that have to hold onto rocks and the bottom may have suction-cup like structures on their bodies. An ecosystem is a system that's made up of both living organisms and non-living things, which depend on each other to survive. A lotic ecosystem can be any kind of moving water, such as a run, creek, brook, river, spring, channel or stream. >> >> Lotic habitats include rivers, streams, and brooks, and lentic habitats include lakes, ponds, and marshes.
