Which one of the following is not a functional unit of an ecosystem:
1 Productivity
2 Stratification
3 Energy flow
4 Decomposition
Explanation:
Stratification is formation of different layers of strata. It is a functional unit of forests. It is in different communities and is different for different types of habitat. Four important functional unit aspects of the ecosystem:- (i) Productivity (ii) Decomposition (iii) Energy flow (iv) Nutrient cycling

In a population, when the growth rate reached to its maximum it is called
1 carrying capacity
2 biotic potential
3 positive interactions
4 negative growth
Explanation:
In a population, when the growth rate reached to its maximum it is called biotic potential. The biotic potential is determined by the quantity of offspring produced and the frequency with which they reproduce.

The amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis is called:
1 Secondary production
2 Primary production
3 Gross primary production
4 Net primary production
Explanation:
The amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis is called Primary Production. Biomass is renewable organic material that comes from plants and animals. Biomass is also called biogas or biofuel.
The ecosystem has the maximum biomass is forest ecosystem. The forest ecosystem has the largest total biomass, which represents about $70 \%$ of whole terrestrial ecosystem.
