This offers an opportunity for commercial biological production of these substances.

Marshes have extremely high levels of biological production, some of the highest in the world, and therefore are important in supporting fisheries.

Thus sea-ice algae provide food resources for higher trophic level organisms in seasons and regions where water column biological production is low or negligible.

But they said they were persuaded that it was a mobile lab for biological production.

A significant biological production of black carbon has recently been identified, especially under moist tropical conditions.

(One novel possibility: advances in genetic science might yield biological production of hydrogen from microbes.)

Methanogenesis is the biological production of methane.

There are extensive areas of mangrove and seagrass in the estuary, resulting in high biological production.

The biological production of hydrogen fuel has been a topic of research since at least the 1970s.

Another source for biological production of hydrogen fuel is algae.
