Question

Which is not a functional unit of an ecosystem

• A. Productivity
• B. Decomposition
• C. Energy flow
• D. Stratificaton

Answer 1

The Correct Option is D

our important functional aspects of the ecosystem are productivity, decomposition, energy flow and nutrient cycling.

Answer 2

A functional unit of an ecosystem is not stratification. It may be found in several communities and varies depending on the kind of environment. Horizontal stratification, for example, is evident in deep ponds and lakes, whereas vertical stratification is seen in seas.
The ecosystem has an inherent tendency to survive. This is made feasible by the structural components performing a range of duties. The ecosystem's components are observed to work together to maintain its survival.
The ecosystem's primary functional features are: - Productivity - Decomposition- Flow of Energy- Nutritional cycling
Productivity is the rate at which biomass is produced. There are two forms of productivity in an ecosystem: primary productivity and secondary productivity.
Decomposition: While productivity comprises synthesis and construction processes, decomposition, which involves the breakdown of complex organic matter into inorganic raw materials like CO₂, H₂O, and other nutrients by decomposers, is equally significant. The top layer of soil in terrestrial habitats and the bottom of marine bodies are the primary sites of decomposition.  Detritus is the staple for decomposition and consists of dead remnants such as leaves, bark, flowers, and animal remains, including feces.
Energy flow is the sequential process of the flow of energy in an ecosystem as it passes through a sequence of creatures. Except for the deep-sea Hydrothermal environment, the sun is the only source of energy for all ecosystems on Earth.
