tropical rain forest produces the most bio mass….
Which ecosystem life zone produces the most biomass each year despite its low NPP?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
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.
What is the typical percentage of high quality energy loss in transfers from one trophic level to the next?
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.
What is the term for the portion of the Earth’s atmosphere hydrosphere and geosphere where life is found?
What is the term for the portion of the earth’s atmosphere, hydrosphere, and geosphere where life is found? biosphere. While the troposphere is 11 miles thick above sea level at the tropics, it is only four miles thick above the North and South poles.
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.
What 3 ecosystems have the highest productivity?
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).
What has the most biomass in an ecosystem?
The trophic level that contains the greatest biomass in most ecosystems is the producers.
Which biome has the most biomass?
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.
In which biome is the highest biodiversity found?
Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.
What trophic level contains the greatest biomass in most ecosystems explain why this occurs?
The tropic level that contains the greatest biomass in most ecosystems are producers. This occurs because producers get there energy from the sun, the sun is the most available resource and so there are the most at that level.
Why is the productivity greater than the annual increase in biomass of herbivores in an ecosystem?
Low biodiversity due to lots of shade, which limits food for herbivores. … The annual productivity of any ecosystem is greater than the annual increase in biomass of herbivores in the ecosystem because? During each energy transformation, some energy is lost.
Why is only 10% of energy stored in biomass at each trophic level transferred up to the next level where is the rest?
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
