for WXYZ

An estimate is like a approximation, judgement decision or a guess at something.in numbers or amount.
Primary productivity<span> is the rate at which energy is converted by photosynthetic and chemosynthetic autotrophs to organic substances. The total amount of</span>productivity<span> in a region or system is gross </span>primary productivity<span>.
</span>Secondary production<span> is the generation of biomass of heterotrophic (consumer) organisms in a system. This is driven by the transfer of organic material between trophic levels, and represents the quantity of new tissue created through the use of assimilated food.
</span>Hence,the statement, "<span>The rate of primary productivity is equal to the rate of secondary productivity" , is a FALSE statement.</span>
