Which of the following is primarily responsible for limiting the number of trophic levels in most ecosystems? Decomposers compete with higher-order consumers for nutrients and energy.
Which of the following are responsible for the conversion of most organic material into CO2 which can be utilized in primary production *?
D) Producers, primary consumers, secondary consumers, and decomposers. E) Producers, primary consumers, secondary consumers, top carnivores, and decomposers. Which of the following are responsible for the conversion of most organic material into CO2, which can be utilized in primary production? A) Autotrophs.
Which of the following ecosystems has the greatest productivity?
Tropical rainforests Tropical rainforests show the highest productivity in terrestrial ecosystems.
What is 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).
Which type of ecosystem accounts for most of the net primary productivity on Earth even though it has a low average net primary productivity?
Explanation: The open oceans account for most of the net primary productivity on the planet even though they have one of the lowest average net primary productivities which cover by far the most area on earth.
Which of the following ecosystems has the greatest primary productivity?
Coral reef ecosystem has highest gross primary productivity due to availability of large number of autotrophs per unit area.
Why is terrestrial primary productivity higher in equatorial climates?
Why is terrestrial productivity higher in equatorial climates? –Productivity increases with water availability.
Which biome has the highest primary productivity?
Tropical forests Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.
Which of the following biomes are more productive in terms of net primary productivity?
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. The tropical seasonal forests also fall in the range of having high primary productivity.
Which of the following have highest primary productivity?
Forest Ecosystem: It has the highest primary productivity.
What are the top 3 most productive ecosystems?
In terrestrial ecosystems the order of productivity in decreasing order is 1. Swamps, marshes, tropical rain forests (most productive), 2. Temperate forest, 3. Northern coniferous forest (taiga), 4.
Which biome has the largest NPP and 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.
Where is NPP highest in the ocean?
NPP is high in coral reef since the high light intensity and warm water allow rapid photosynthesis.
Which one of the following is the most productive ecosystem?
Tropical rainforest Tropical rainforest shows the maximum diversity and also the maximum productivity.
Why does the equator have high primary productivity?
Answer and Explanation: Net primary production is higher at the equator because this area is warmer, which allows photosynthesis to occur year-round, and also because this region of the planet receives more of the sun's energy per square metre than other higher latitude regions of the planet.
What is net primary productivity NPP )?
Definition. The amount of carbon retained in an ecosystem (increase in biomass); it is equal to the difference between the amount of carbon produced through photosynthesis (GPP) and the amount of energy that is used for respiration (R).
What is the net primary productivity?
Definition. The amount of carbon retained in an ecosystem (increase in biomass); it is equal to the difference between the amount of carbon produced through photosynthesis (GPP) and the amount of energy that is used for respiration (R).
Which biome has the highest total primary production?
the 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. The tropical seasonal forests also fall in the range of having high primary productivity.
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.
What are the most productive ecosystems on Earth?
Wetlands and Nature
- Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. …
- Wetlands play an integral role in the ecology of the watershed. …
- Wetlands' microbes, plants and wildlife are part of global cycles for water, nitrogen and sulfur.
What kind of ecosystem is the most productive?
Tropical Rain Forests:
- This forest has high soil moisture, high availability of nutrients so it has high net productivity.
- Hence, they are the most stable ecosystem.
- In terms of Net Primary Productivity (NPP) per unit area, the most productive systems are tropical rain forests.
Which biome has the highest primary productivity per unit area?
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.
Where is net primary productivity the highest equator?
Answer and Explanation: Net primary production is higher at the equator because this area is warmer, which allows photosynthesis to occur year-round, and also because this region of the planet receives more of the sun's energy per square metre than other higher latitude regions of the planet.
Which is the largest ecosystem on earth?
The World Ocean The World Ocean is the largest existing ecosystem on our planet. Covering over 71% of the Earth's surface, it's a source of livelihood for over 3 billion people.
Which part of ecosystem is the most productive?
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 area of the ocean has the highest net primary productivity?
Higher chlorophyll concentrations and in general higher productivity are observed on the equator, along the coasts (especially eastern margins), and in the high latitude ocean (Figure 4a and b).
What is net primary productivity of an ecosystem?
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.
