The correct answer is Streams, River and Spring.

  • The pond is not an example of a Lotic ecosystem.

Key Points

  • The lotic water is a classification of the freshwater bodies on the basis of the flow of the water.
  • The lotic water is composed of flowing water bodies.
  • The water of these types of water bodies does not stay in one place but rather moves or flows from one place to another.
  • In the first option, we are given streams, rivers, and springs.
    • Streams, rivers, and springs are all flowing bodies of water.
    • Hence, these are all examples of lotic water.
  • A river is a flowing body of water.
    • Lakes and ponds are still bodies of water.
    • Hence, the river is an example of lotic water and the lake and ponds are examples of lentic water.
  • Swamps and lakes are both still bodies of water.
    • Hence, these are both examples of lentic water.
  • ​​Lakes and ponds are both still bodies of water.
    • Hence, these are both examples of lentic water.
    • From the above information, we can conclude that the streams, rivers, and springs are examples of lotic water.

Additional Information

  • The freshwater bodies or the freshwater ecosystem are classified into two classes on the basis of the flow of the water.
  • These two classes are lentic and lotic water. Lentic water is also known as the lacustrine ecosystem or the still water ecosystem.
  • It consists of those freshwater bodies, in which the water is still and does not flow.
  • Hence, a lentic ecosystem is a body of standing water.
  • Lotic water consists of those freshwater bodies, in which the water is moving and flows from one point to another.
