What are the most productive and least productive ecosystems?
Globally, patterns of primary productivity vary both spatially and temporally. The least productive ecosystems are those limited by heat energy and water like the deserts and the polar tundra. The most productive ecosystems are systems with high temperatures, plenty of water and lots of available soil nitrogen.
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 is not most productive ecosystem?
Desert :- this ecosystem has very low availability of nutrients so this is the reason they have very low net primary productivity. So, it is not a stable ecosystem.
Which ecosystem is biologically least productive?
-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.
What are the three least productive habitats?
The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome. These biomes include habitats that have extreme temperatures and very limited precipitation, which results in very low production of new biomass.
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.
Which world ecosystems are most productive in terms of biomass which are the least productive?
What units are used in this figure to quantify biomass accumulation? The most productive ecosystems are tropical rain forests and estuaries. The least productive ecosystems are desert and open ocean. The units to quantify biomass accumulation are 1,000/kcal/m2/year.
Which is the smallest ecosystem?
The Temperate Grassland is the smallest ecosystem in the world as well as on earth. The area of this grassland occupied by Tundra.
Which is the least productive terrestrial ecosystems on Earth?
Desert and Tundra Biomes, limited by precipitation and temperature respectively, contain the least productive ecosystems.
Which of the following is most productive?
In terms of net primary productivity tropical rain forest is at the top followed by coral reef, easturies and desert and ocean.
Is sugarcane field a productive ecosystem?
The most productive ecosystem are coral reef ecosystem due to structural complexity. It is also called as tropical rain forests. It includes temperate and tropical forests. … Sugarcane is the most productive agroecosystem.
Which of the following is least productive ecosystem desert?
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. But on a global basis, aquatic ecosystems occupy more space on earth than any other biome and have good productivity in surface layers, which are euphotic.
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.
