Which of the following terrestrial biomes has the highest primary productivity per unit?
tropical rainforest biome As you might expect, the terrestrial biome with the highest level of primary productivity is the tropical rainforest biome with around 2,200 grams of biomass per square meter per year.
Which biome has a higher net productivity Why?
The tropical rainforest biome is the biome which has the highest net primary production. Net primary productivity is the accumulation of biomass. It occurs when the rate of photosynthesis in plants exceeds their rate of respiration.
What is high 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 of the following terrestrial biomes has the highest net primary productivity quizlet?
Which of the following terrestrial biomes has the highest primary productivity per unit area? Tropical rain forests have a yearlong growing season and more than 60 inches of rain per year. The warm climate and the rainfall leads to high levels of photosynthesis in the numerous plant species that inhabit the biome.
Which terrestrial ecosystem has the highest NPP?
tropical rainforests The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
Which is the most productive terrestrial ecosystem?
Tropical rainforests Tropical rainforests show the highest productivity in terrestrial ecosystems.
Where is net primary productivity highest?
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 primary productivity?
In an ecosystem, primary productivity refers to the accumulation of energy in terms of biomass. In aquatic ecosystems, coral reefs have the highest productivity. Tropical rainforests show the highest productivity in terrestrial ecosystems.
Which of the following biomes is most productive?
tropical rain forest is the most productive biome on earth.
Which has the highest net primary productivity?
tropical rainforests The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
Which ecosystem has highest primary productivity?
Coral reef ecosystem has highest gross primary productivity due to availability of large number of autotrophs per unit area.
Where is net primary productivity the highest quizlet?
Cold and dry biomes have the highest net primary production. Primary consumers convert solar or chemical energy into energy stored in the bonds of organic sugars.
What areas have high primary productivity?
In general, swamps and marshes have the highest primary production of all the world's ecosystems. Primary production of all wetland types varies from 600-2000 gC/m2/y.
Which biome has the highest net primary productivity quizlet?
Warm and wet biomes have the highest net primary production , and cold , dry biomes the lowest. – Primary production is the organic matter or biomass that remains after celluar respiration.
Which of these terrestrial ecosystems has the highest net primary productivity quizlet?
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? A) Oceans contain greater concentrations of nutrients compared to other ecosystems.
Which of these ecosystems has the highest net primary?
The correct answer is Rainforest.
Why do swamps and marshes have high NPP?
Freshwater marshes and swamps are known to possess some of the highest net primary production of any ecosystem on earth (Westlake 1963;Whittaker 1975;Wetzel 1992; Rocha and Goulden 2009) , and this may be partly caused by the widespread dominance of tall graminoids with such vertically aligned leaves, together with …
Which of the following terrestrial biomes has the highest primary productivity per unit area quizlet?
Which of the following terrestrial biomes has the highest primary productivity per unit area? A temperate grassland biome has a gross primary productivity of 3,480kilocalories/meter2/year and a net primary productivity of 2,000kilocalories/meter2/year.
Which location would have the highest net primary productivity?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
Which of these ecosystems has the highest primary productivity?
Coral reef ecosystem has highest gross primary productivity due to availability of large number of autotrophs per unit area.
Does temperate grassland have high net primary productivity?
If crops replace forests, these numbers suggest a decrease in NPP, while if crops replace grassland, there may be no big change or a slight increase in NPP….Jackson and Jackson (2000)
| Land type | Average NPP (tons per km2 per year) |
|---|---|
| Boreal forest | 800 |
| Cultivated land | 650 |
| Temperate grassland | 600 |
| Continental shelf | 360 |

Which biome has the highest net primary productivity in part because of consistently warm temperatures and abundant sunlight?
However, the driest month of a tropical rainforest can still exceed the annual rainfall of some other biomes, such as deserts. Tropical rainforests have high net primary productivity because the annual temperatures and precipitation values support rapid plant growth.
Which biome would have the highest net primary production quizlet?
Cold and dry biomes have the highest net primary production. Primary consumers convert solar or chemical energy into energy stored in the bonds of organic sugars.
Do cold and dry biomes have the highest net primary production?
Biomes are characterized by their climates as well as typical plant and animal life. Biomes vary in their rates of net primary production. Warm and wet biomes have the highest net primary production, and cold, dry biomes have the lowest.
