What is different between logic and lentil ecosystem​

. Lentic Aquatic Systems:

Lentic aquatic systems are those which contain stagnant waters. These are usually formed in small or large depressions on earth's surface which possess no exit for the water to flow out. Lentic systems, therefore, are closed systems. Whatever gets in it, rarely gets out. It has to decay, decompose or persist as such within the lentic body. Natural processes in the long run change such a body into a swamp or a marsh, a wetland and finally to dry land. Small puddles, ponds and lakes are familiar examples of such systems.

The Lotic Aquatic Systems:

Lotic aquatic systems are those systems which contain flowing waters. The mass of water in these systems is in a state of perpetual motion. Streams and rivers are familiar examples of such systems. The basic function of these lotic bodies of water is to carry the surplus rain water back to the sea. The total amount of water which streams and rivers of the world carry to the oceans amounts to almost 25 cms of rains distributed evenly over the land surface.
