Functional Unit of Ecosystem

Functional unit of ecosystem comprises different components that work together to ensure the smooth functioning of the ecosystem. These components include productivity, decomposition, energy flow, and ecological pyramids.

Productivity
- Productivity refers to the rate at which energy is captured by producers in an ecosystem through photosynthesis or chemosynthesis.
- It is a crucial aspect of the ecosystem as it forms the basis of the food chain by providing energy for all other organisms.

Decomposition
- Decomposition is the process in which organic matter is broken down by decomposers into simpler substances like nutrients.
- This process is essential for recycling nutrients back into the ecosystem, allowing them to be used by plants again.

Energy Flow
- Energy flow involves the transfer of energy from one trophic level to another in an ecosystem.
- It is crucial for sustaining life within the ecosystem, as energy is passed along the food chain to support the different organisms.

Ecological Pyramids
- Ecological pyramids are graphical representations of the trophic structure of an ecosystem, showing the flow of energy or biomass through different trophic levels.
- They provide important insights into the relationships between different organisms in the ecosystem.

In conclusion, while productivity, decomposition, and energy flow are key components of the functional unit of an ecosystem, ecological pyramids are not considered a component of this unit. Ecological pyramids are used to illustrate the trophic structure of an ecosystem rather than actively participating in its functioning.

The interaction of biotic and abiotic components results in a physical structure that is characteristic of each type of ecosystem. The important structural features include
