-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.
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.
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.
Which of these ecosystems has the lowest net primary productivity?
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.
Are coral reefs least productive ecosystem?
In oceans, there are lots of nutrients but no sufficient sunlight is available in deep areas hence, oceans have least productivity. Grasslands are less productive ecosystem with annual productivity of 200-100gm/m2. Maximum productivity can be seen in coral reefs followed by estuaries.
Which is the most productive ecosystem?
Thus, tropical rain forests are the most productive ecosystem.
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 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 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.
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.
What ecosystems have the least amount of productivity per unit area?
What ecosystems have the least amount of productivity per unit area? Tundras, the open ocean, desert scrubs, and the extreme desert. What ecosystems are the most productive in the world? The open ocean and tropical/temperate rain forests.
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…
Is sugarcane field most productive ecosystem?
The most productive ecosystem are coral reef ecosystem due to structural complexity. It is also called as tropical rain forests. … Sugarcane is the most productive agroecosystem.
Which of the following is the area of least productivity?
Which of the following is the area of least productivity? Explanation: D The area of least productivity in the ocean is the area that does not receive any sunlight, so photosynthesis cannot occur. The area without any sunlight is called the aphotic zone.
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.
