Question

Which of the following is the most stable ecosystem?
(a) Mountain
(b) Dessert
(c) Forest
(d) Ocean

Answer 1

The good ecosystem entails plants plus animal genera which interact with one another and also with the environment. Some ecosystems are vast and possess certain compounds that will contribute to resistance during small shifts in the environment and hence will not alter the life present in that ecosystem.

Complete answer:
As we know that the ocean environment has fewer changes as compared to other systems, Therefore, oceans are considered to be the most stable and reliable ecosystem.
The two main ecosystem components are the function and structure of the ecosystem. The structure of the ecosystem consists of two main components: the biotic and the abiotic system.
Biotic system: It comprises the complete living system that exists in this world.
Abiotic system: It comprises the basic constituents such as water, soil, oxygen, carbon dioxide, and other organic substances.
The function of the ecosystem are:
- The ecosystem controls various vital ecological processes, sustains life forms, and provides stability.
- The cycling of nutrients and energy amongst biotic and abiotic components is a function of the ecosystem.
- The balance between different trophic levels is maintained by the ecosystem.
- The cycling of minerals in the biosphere is a function of the ecosystem.
- The abiotic constituents will aid the synthesis of organic substances that are engaged in the energy exchange.
- The ecosystem is said to be stable if both the function as well as the structure of the ecosystem remains unaltered in the long run. The salinity of the ocean confers the stability of the ocean. Also, the oceans are deep, they run continuously, and they are enormous. Additionally, the oceans have an almost unaltered amount of dissolved oxygen, temperature, light and thereby they remain unaffected and can withstand any small changes.
So, the correct answer is ‘Ocean’.

Note: Over the years it is observed that various geological and anthropogenic activities had impacted the desert, forest, and mountains. These activities include earthquakes, volcanic eruptions, deforestation, forest fire, etc., But the oceans are noticed to be comparatively stable for a long time period.
