Productivity of an Ecosystem

In the equation GPP - R = NPP

GPP is Gross Primary Productivity

NPP is Net Primary Productivity

R here is :

What is the percentage of primary productivity of oceans?

The productivity of ocean is less because

The amount of biomass or organic matter produced per unit area over a period of time by plants during photosynthesis is known as

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

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.
