Question

Aquarium is not a natural ecosystem.
a) True
b) False

Answer 1

Hint: Total living (biotic) and nonliving (abiotic) components of the environment present in a particular area is called an ecosystem. It can be natural as well as artificial. Natural ecosystems can be terrestrial or aquatic ecosystems. Artificial ecosystems are man-made ecosystems.

Complete answer:
-In an ecosystem, communities or living organisms interact with their physical environment in such a way that there is a well-defined flow of energy forming clear trophic levels and material cycles within this ecosystem.
-An ecosystem may be temporary as a freshwater pool or a field or permanents like a forest or sea.
-Terrestrial natural ecosystem includes forest, grassland, tree, desert ecosystem.
-Aquatic natural ecosystem is of two types-Lentic and lotic ecosystems.
-Lentic ecosystem includes stagnant water, lake, pond, swamp.
-Running a freshwater ecosystem like a river is an example of a lotic water system.
-Artificial ecosystems are man-made. These can be terrestrial like cropland or aquatic like an aquarium.

Additional information:
-Ecosystem is the smallest structural and functional unit of nature.it is a self-regulatory and self-sustaining unit.
-Each trophic level controls the other trophic level in an ecosystem. A science of self-control or homeostasis is present in an ecosystem. It is called cybernetics.
-There is an energy source for all living organisms in an ecosystem.

So, the correct answer is ‘True’.

-The boundaries of the ecosystem are indistinct and have an overlapping character over each other.

Note:
The term “Ecosystem” is coined by A.G Tansley. E.P Odum is known as the father of ecosystem ecology. On the basis of size, ecosystems are classified into the mega ecosystem, macro ecosystem, microecosystem, and nano ecosystem.
