Hi Amit

The direct use value of biodiversity include the consumptive use and productive use values. Now If tell you about consumptive use value then it is the value placed on natures products that are consumed directly that is without passing through a market.
Direct consumption involves recreation, sport fishing and game viewing, the consumptive use value is the whole recreational experience.

While the indirect use value of biodiversity deal primarily with the functions of ecosystems , are not normally reflected in national economic systems but they far outweigh direct values. These values tend to reflect the value of biological diversity to society at large rather than to individuals or corporate entities. Direct values often derive from indirect values, because plants and animals are supported by the services provided by their environments .

I hope that it helps you


Thank you
