You asked: Which aquatic ecosystem has the highest NPP?

In the aquatic ecosystem, coral reefs show the highest gross primary productivity. Large numbers of aquatic phototrophs and phytoplankton contribute to the productivity of the ecosystem.

Which aquatic biome has the highest NPP?

Biomes with High Primary Productivity

These highly productive areas have an average annual net primary production of over 1,000 grams per square meter per year. The aquatic biome with the highest level of primary productivity is the coral reef biome with around 2,500 grams of biomass per square meter per year.

What ecosystems have the highest NPP?

The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.

Which kinds of ecosystems have the highest NPP Why?

Main points

  • Tropical rain forests have high NPP and the highest biodiversities of any terrestrial ecosystems. …
  • In rain forests, plants have constant high levels of water and light (at canopy level) and the nutrient supply is as high as possible, due to rapid decomposition.

Which aquatic ecosystem has the highest net primary productivity quizlet?

COLD AND DRY biomes have the highest net primary production. WEATHER describes the average conditions, including temperature and precipitation, over long periods in a given area. Under water, photosynthesis by aquatic plants and phytoplankton is mostly limited by the amount of OXYGEN available.

What biomes have high NPP low NPP Why?

Biomes with more vegetation have higher NPP levels (tropical rainforest has the most). Important because it can be an indicator for studying health of diff plants.

Which season has the highest NPP?

In mid-latitudes, productivity is obviously tied to seasonal change, with productivity peaking in each hemisphere’s summer. The boreal forests of Canada and Russia experience high productivity in June and July and then a slow decline through fall and winter.

Why do swamps have high NPP?

Net primary production (NPP) is highest in wetlands receiving nutrient enrichment or with high nutrient turnover. The degree, duration, and periodicity of flooding affect wetland productivity more than rainfall or temperature. Drainage can promote enhanced productivity by increasing nutrient mineralization.

Which terrestrial and aquatic ecosystems have the highest NPP Why do you think this is?

What 3 ecosystems have the lowest NPP?

The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.

What are the two most productive aquatic ecosystems?

List two of the most productive ecosystems or aquatic life zones and two of the least productive. The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.

Does agricultural land have high NPP?

If crops replace forests, these numbers suggest a decrease in NPP, while if crops replace grassland, there may be no big change or a slight increase in NPP.
