Apart from bacteria, the total global live biomass has been estimated as 550 or 560 billion tonnes C, most of which is found in forests. Shallow aquatic environments, such as wetlands, estuaries and coral reefs, can be as productive as forests, generating similar amounts of new biomass each year on a given area.
Which ecosystem produces the most biomass annually?
tropical rain forest produces the most bio mass….
Which ecosystem life zone produces the most biomass each year despite its low NPP?
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). Figure 4. Net Primary Production per unit area of the world’s common ecosystems.
Which aquatic biome produces the most biomass each year?
The aquatic biome with the highest level of primary productivity is the coral reef biome with around 2,500 grams of biomass per square meter per year.
Which of these ecosystems accounts for the largest amount of Earth’s net primary productivity?
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.
What animal makes up the most biomass?
The most successful animal species, in terms of biomass, may well be Antarctic krill, Euphausia superba, with a fresh biomass approaching 500 million tonnes, although domestic cattle may also reach these immense figures.
Which trophic level has the greatest biomass?
The trophic level that contains the greatest biomass in most ecosystems is the producers.
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 or life zone produces the highest net primary productivity per year?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
Which ecosystem produce the highest annual net primary productivity?
Solution(By Examveda Team)
The tropical rainforest has highest annual net primary productivity (9000 K cal / m2 / yr).
In which biome is the highest biodiversity found?
Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.
Which trophic level has the least biomass?
The trophic level that has the least biomass is usually the tertiary consumers.
What are examples of biomass?
Biomass is a renewable energy source because we can always grow more trees and crops, and waste will always exist. Some examples of biomass fuels are wood, crops, manure, and some garbage. When burned, the chemical energy in biomass is released as heat.
Which of the following is likely to have the greatest biomass in an ecosystem?
Explanation: In general, the higher the trophic level (increasingly apex predators), the lower the biomass. Therefore, the lowest trophic level has the greatest biomass, and those are the producers. These include things like grass, trees, and flowers.
Which of the following are the major decomposers in ecosystems?
Major decomposers in the ecosystem include bacteria and fungi. One would wonder what do these decomposers eat. Well, decomposers feed upon the dead matter.
What limits the number of trophic levels in most ecosystems?
On average, only about 10 percent of energy stored as biomass in a trophic level is passed from one level to the next. This is known as “the 10 percent rule” and it limits the number of trophic levels an ecosystem can support.
