Which ecosystem has the lowest primary productivity per square meter?

So, the correct option is ‘Open Ocean’.

Which ecosystem has lowest primary productivity unit area?

The rate at which plants and other photosynthetic creatures generate organic substances in an ecosystem is referred to as primary productivity. Deserts, tundra, the open ocean, and the lakes and streams biome all have the lowest amounts of primary productivity. As a result, the right answer is ‘Open Ocean.

Which ecosystem has lowest production?

-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 marine zone has the lowest rate of primary productivity?

the marine zone with the lowest rate of photosynthesis would likely be the B) abyssal zone as this zone is furthest from the surface and therefore…

Which of the following has the least net primary productivity NPP )?

The correct answer is Temperate grasslands. Temperate grasslands are characterized as having grasses as the dominant vegetation. Trees and large shrubs are absent, therefore it has the lowest mean net productivity in the category of grasslands.

Which is the smallest ecosystem?

The earth environment contains four components namely Lithosphere, Biosphere, Hydrosphere and Atmosphere. As the biosphere is comprised of a group of ecosystem linked together, hence ecosystem is considered as the “smallest unit of the biosphere.

Which ecosystem has the lowest average primary productivity quizlet?

Tropical oceans have a constant low level of productivity due to the high influx of fresh water due to rain. Tropical oceans have a constant low level of productivity due to low salinity.

What 3 ecosystems have the highest productivity?

The world’s ecosystems vary tremendously in productivity, as illustrated in the following figures. In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests (see Figure 4).

Which of the following has highest net primary productivity per square Metre?

In terms of net primary productivity tropical rain forest is at the top followed by coral reef, easturies and desert and ocean.

Where is the rate of primary production the least?

About 40 to 85 percent of gross primary productivity is not used during respiration and becomes 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 aquatic biome has the lowest rates of primary productivity photosynthesis?

Although there are plants adapted to live in these biomes, they are slow growing and do not produce a large amount of biomass. The aquatic biomes with the lowest levels of primary productivity are the open ocean and lakes and streams.

Which lake zone does not receive sunlight?

The limnetic zone is the open water area where light does not generally penetrate all the way to the bottom. The bottom sediment, known as the benthic zone, has a surface layer abundant with organisms.

Which of these ecosystems has the highest primary productivity per square meter quizlet?

How is it that the open ocean produces the highest net primary productivity of Earth’s ecosystems, yet net primary productivity per square meter is relatively low? Oceans contain greater concentrations of nutrients compared to other ecosystems. Oceans receive a greater amount of solar energy per unit area.

Which ecosystem has highest annual net primary productivity?

The tropical rainforest has the highest annual net primary productivity (9000 Kcal/m2/yr).

Which one of the following ecosystems has the highest net primary productivity?

The correct answer is Rainforest.
