Which ecosystem among these has the highest Gross Primary Productivity (GPP)?
Open in App
Solution
The correct option is B Coral reefs
Gross Primary Productivity (GPP) is the amount of carbon fixed during photosynthesis by all producers in the ecosystem.
Coral reefs are large underwater structures composed of the skeletons of colonial marine invertebrates called corals. In aquatic ecosystems, coral reefs show the highest GPP, aquatic phototrophs and phytoplankton contribute to the productivity of this ecosystem.
In the case of terrestrial ecosystems, tropical rainforests have the highest productivity followed by marshes, mangroves, grasslands etc.
Biomes with the lowest levels of primary productivity include deserts, tundra, the open ocean etc.
