Answer

Functional Components of Ecosystem Change During Ecological Succession

Dominance:
During ecological succession, the dominant species in an ecosystem can change. Initially, pioneer species colonize the area, and as succession progresses, they are replaced by more competitive and dominant species. This change in dominance can significantly alter the structure and function of the ecosystem.

Energy Usage Efficiency:
Energy usage efficiency may change during ecological succession. Pioneer species often have low energy usage efficiency as they are adapted to harsh conditions. However, as succession proceeds, more efficient energy users replace them, leading to an increase in overall energy usage efficiency in the ecosystem.

Species Diversity:
Species diversity tends to increase during ecological succession. Initially, the pioneer species are limited in number and adapted to specific conditions. However, with time, more species are able to colonize the area, leading to an increase in species diversity. This increase in diversity is essential for the stability and resilience of the ecosystem.

Vegetation:
Vegetation composition and structure change significantly during ecological succession. Pioneer species, such as mosses and lichens, are gradually replaced by larger plants like shrubs and trees. This change in vegetation affects various ecological processes, including nutrient cycling, habitat provision, and energy flow.

Stratification:
Stratification refers to the vertical layering of vegetation in an ecosystem. During ecological succession, the stratification of vegetation can change. Initially, there may be little to no stratification, but as succession progresses, taller plants emerge, creating distinct vertical layers within the ecosystem.

Nutrient Conservation:
Nutrient conservation improves as ecological succession advances. Pioneer species often have limited nutrient requirements and are not efficient at nutrient conservation. However, as more complex and diverse species establish, nutrient cycling becomes more efficient, leading to increased nutrient conservation in the ecosystem.

Productivity:
Productivity generally increases during ecological succession. Pioneer species have lower productivity due to their adaptation to harsh conditions and limited resources. However, as succession progresses, more productive species replace the pioneers, leading to higher overall productivity in the ecosystem.

Decomposition:
Decomposition rates can change during ecological succession. Initially, decomposition may be slow due to limited microbial activity and nutrient availability. However, as more organic matter accumulates and nutrient cycling improves, decomposition rates typically increase, facilitating nutrient release and cycling in the ecosystem.

Overall, ecological succession leads to significant changes in various functional components of an ecosystem. These changes are necessary for the development of a stable and diverse ecosystem that can efficiently utilize energy, conserve nutrients, and support a wide range of species.
