-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.
How many are considered least productive ecosystems?
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 of the following ecosystem is least productive in terms of NPP?
In terms of NPP per unit area the most productive ecosystems in the world are estuaries, swamps and marshes, followed by the tropical rain forests, coral reefs, temperate deciduous forests and grasslands. The tundras, open oceans and deserts are the least productive.
What is the most productive ecosystem?
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 biomes has the least gross primary productivity?
The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.
Which of the following has the lowest mean net primary productivity?
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 of following ecosystem is most productive in terms of net productivity?
In terms of net primary productivity tropical rain forest is at the top followed by coral reef, easturies and desert and ocean.
Which 3 ecosystems have the highest productivity and which 3 have the lowest productivity?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
Which one of the following are most productive ecosystem except?
Solution: Answer: DSolution: Tropical rainforest shows the maximum diversity and also the maximum productivity.
Is Deep Sea least productive ecosystem?
The primary factors affecting the productivity of any ecosystem are sunlight, carbon dioxide, water, and nutrients. … -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 forest biome has the lowest productivity?
So, depending on the amount of rainfall and nutrient distribution within a desert, certain areas may cause a larger GPP and NPP than others. Overall, the productivity of deserts is the lowest of all the biomes.
