Ecosystem
It is the interaction of living things among themselves and with their surrounding environment.
There are two basic ecosystems − terrestrial and aquatic.
Structure of Ecosystem
The interactions between the various biotic and abiotic factors of an ecosystem lead to the maintenance of the ecosystem.
Stratification is the vertical distribution of the different species occupying the different levels. For example, trees occur at a higher level then shrubs.
The various aspects taken into consideration to study the functioning of ecosystem are:
Productivity
Decomposition
Energy flow
Nutrient cycling
