Productivity of an Ecosystem

The rate of formation of new organic material by rabbit in a grassland ecosystem is called:

In an ecosystem, the rate of production of organic matter during photosynthesis is termed

Secondary productivity is the rate of formation of new organic matter by $\underline{ }$

Which type of ecosystem has the lowest productivity?

The primary productivity of an ecosystem depends on

A. Available solar radiations.

B. Availability of nutrients in soil.

C. Photosynthetic capacity of producers.

D. Abiotic factors of that area.

The annual net primary productivity of terrestrial surface is           (dry weight) of organic matter.

What is the biomass available for consumption to heterotrophs and the rate of formation of new organic matter by consumers defined as?

The rate at which light energy is transformed into chemical energy of organic molecules, is the ecosystem's

The given graph shows the productivity of an aquatic ecosystem measured in terms of dissolved oxygen produced and consumed by green plants and photosynthetic algae where $\mathrm{PS}=$ photosynthesis and $\mathrm{R}=$ respiration.

What will happen during the algal bloom?

 What are the elements present in an aquatic ecosystem?

The available biomass for the consumption by heterotrophs (herbivores and decomposers) is:

Which of the following is an incorrect statement?

Select the most productive ecosystem.

With respect to the most productive ecosystem, select the odd one out.

The rate of biomass production in terms of energy is expressed as:

Who is the contributor to the largest ecosystem in the world ?

The importance of ecosystem maintenance lies in

The rate of formation of new organic matter by rabbit in a grassland, is called

 Productivity is the rate of production of biomass expressed in terms of 

(i) $\left({\mathrm{kcalm}}^{-3}\right){\mathrm{yr}}^{-1}$
(ii) $g^{-2}y{r}^{-1}$
(iii) $g^{-1}y{r}^{-1}$
(iv) $\left({\mathrm{kcalm}}^{-2}\right){\mathrm{yr}}^{-1}$
