Question

Lotic ecosystem refers to
A. Static water system
B. Ecosystem of flowing water
C. Ecosystem of estuaries
D. Deep marine water system

Answer 1

Hint: An ecosystem is a geographical area in which plants, animals, and other species, as well as weather and topography, interact to generate a living bubble. Ecosystems comprise both biotic and abiotic elements, or living and nonliving components. Rocks, temperature, and humidity are examples of abiotic variables.

Complete answer:
Lentic (from the Latin lentus, meaning slow or motionless) refers to still waters like lakes and ponds (lacustrine) or swamps and marshes (paludal), whereas lotic (from the Latin lotus, meaning washing) refers to flowing water habitats like rivers and streams. Biosphere is the single largest ecosystem of the earth.

Lotic ecosystem refers to the ecosystem of flowing water. So the correct answer is (B).

River ecosystems are flowing rivers that drain the landscape, and they involve both biotic (living) and abiotic (nonliving) physical and chemical interactions among plants, animals, and microorganisms. River ecosystems are part of larger watershed networks or catchments, where smaller headwater streams flow into mid-sized streams, which then flow into bigger river networks.

The gradient of the river bed or the current velocity determine the key zones in river ecosystems. Faster moving turbulent water often has higher dissolved oxygen concentrations, which supports more biodiversity than slow-moving pool water.

There are flowing rivers in a Lotic Ecosystem. Creeks, streams, flows, rivers, springs, brooks, and channels are only a few examples. The waters in a Lentic Ecosystem are calm. Ponds, basin marshes, ditches, reservoirs, seeps, lakes, and vernal / ephemeral pools are some examples.

Note:-
Because artificial systems lack the diversity and powerful self-regulatory systems that characterise natural systems, they are more unstable and subject to failure. Artificial ecosystems are similar to natural ecosystems in that they are developed and managed by humans. Artificial ecosystems are far simpler than natural ecosystems, yet they are by far the most familiar environments in human history.
