The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
Which ecosystem has the highest net productivity per area?
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 ecosystem has the highest primary productivity?
Coral reefs ecosystem has the highest gross primary productivity.
Which ecosystem produce the highest annual net primary productivity *?
The tropical rainforest has the highest annual net primary productivity (9000 Kcal/m2/yr). Net primary productivity is the rate at which all the plants in an ecosystem produce net useful chemical energy.
Which ecosystem has the highest net primary productivity per unit area quizlet?
What ecosystems are the most productive in the world? The open ocean and tropical/temperate rain forests.
What is high net primary productivity?
They show net primary productivity, which is how much carbon dioxide vegetation takes in during photosynthesis minus how much carbon dioxide the plants release during respiration (metabolizing sugars and starches for energy). …
What is net primary productivity?
Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it’s the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.
Which ecosystem has highest productivity Upsc?
Tropical rainforest have highest primary productivity and is least in desert.
Which of these ecosystem has the lowest net primary production per square Metre?
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 type of ecosystem has highest average net productivity kcal m2 year?
The most productive ecosystems are fertile estuaries and marshes, coral reefs, terrestrial vegetation on moist alluvial deposits, and intensive agriculture, which can have productivities of 10-25 × 103 kcal/m2/yr.
Which of the following is expected to have the highest value in a grassland ecosystem?
The rate of total capture of energy or the rate of total production of organic material is gross primary productivity while the balance or biomass remaining after meeting the cost of respiration of producers is net primary productivity. Hence, gross productivity has highest value in grassland ecosystem.
