Stratification is :-
1 Identification and enumeration of plant and animal species of an ecosystem
2 Species composition
3 Vertical distribution of different species occupying different levels
4 Active nature of all the components of the ecosystem as a unit
Explanation:
Stratification refers to the formation of vertical layers. Vertical distribution of different species occupying different levels is called as Stratification.

Productivity, decomposition, energy flow and nutrient cycling are the :-
1 Physical structure of ecosystem
2 Functions of ecosystem
3 Only Biotic components of ecosystem
4 Only Abiotic components of ecosystem
Explanation:
Productivity, decomposition and nutrient cycling are the functions of an ecosystem.Productivity is the rate of biomass production, it includes primary productivity and secondary productivity. Decomposition is the process of breakdown of complex organic matter into inorganic substances like \(\mathrm{CO}_{2}, \mathrm{H}_{2} \mathrm{O}\). Nutrient cycling refers to the process of movement of nutrient elements through various components of an ecosystem. Nutrient cycling is also referred as Biogeochemical cycles and it includes gaseous cycles and sedimentary cycles.
