-Oceans contain lots of nutrients but they have no sufficient sunlight reaching in the deep areas, therefore, oceans have the least productivity among all ecosystems.
Which of following is least productive ecosystem?
Least productive ecosystem is desert and deep lake.
Which of the following is least productivity?
Question : Which one of the following exhibits least productivity…
- A. Salty marshes.
- B. Grasslands.
- C. Open oceans.
- D. Coral reefs.
- Answer. C.
- Solution. In oceans, there are lots of nutrients but no sufficient sunlight is available in deep areas hence, oceans have least productivity.
Is Desert a least productive ecosystem?
Very low productivity is present in deserts and arctic regions. In oceans and other aquatic ecosystems, productivity is limited by light as it decreases with depth.
Which is the most productive ecosystem?
Thus, tropical rain forests are the most productive ecosystem.
Which ecosystem has lowest net primary productivity?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
Which is the smallest ecosystem?

Is sugarcane field most productive ecosystem?

Is Coral Reef the most productive ecosystem?
Coral reefs are among the most productive ecosystems on the planet, with the primary producers at the base of the food chain (including corals) supporting their complex food webs.
Is Deep Sea a productive ecosystem?
They estimate that worldwide, deep-sea hydrothermal vent microbial communities can produce more than 4,000 tons of organic carbon each day, the building block of life. That is roughly the same amount of carbon in 200 blue whales — making these ecosystems among the ocean’s most productive on a per volume basis.
Is coral a reef?
Coral reefs are large underwater structures composed of the skeletons of colonial marine invertebrates called coral. … Each individual coral is referred to as a polyp. Coral polyps live on the calcium carbonate exoskeletons of their ancestors, adding their own exoskeleton to the existing coral structure.
Which is the relationship between biomass and NPP?
Primary productivity is the process resulting from photosynthetic activity of the plants and determines biomass accumulation in forests. Net primary productivity (NPP) represents the difference between gross photosynthesis of plant foliage and energy losses due to respiration and mortality of plant tissues.
Which is the least productive terrestrial ecosystems on Earth?
Desert and Tundra Biomes, limited by precipitation and temperature respectively, contain the least productive ecosystems.
Is Deep Sea least productive ecosystem?
-Oceans contain lots of nutrients but they have no sufficient sunlight reaching in the deep areas, therefore, oceans have the least productivity among all ecosystems.
