What are the two most productive aquatic ecosystems? The two most productive are estuaries, swamps and marshes, and tropical rainforests. The two least productive are the open ocean, the tundra and the desert.
In this article :
What ecosystem has the highest net primary productivity?
The highest net primary productivity in terrestrial environments is in wetlands and swamps and in tropical rainforests; it is lowest in the deserts. On the same subject : How to calculate volumetric.
Which 3 ecosystems have the highest productivity? According to the NPP per unit area, the most productive systems are estuaries, wetlands and swamps, tropical rainforests and temperate rainforests (see Figure 4).
Which ecosystem has the highest net primary productivity quizlet per unit area? What types of ecosystems have the highest productivity per unit area? Estuaries, swamps and marshes, tropical rainforests and temperate rainforests.
What are the factors affecting primary productivity?
Net primary productivity varies between ecosystems and depends on many factors. This may interest you : How to calculate productivity rate. These include solar energy intake, temperature and humidity, carbon dioxide levels, nutrient availability and community interactions (eg grazing of herbivores) 2.
What are the four limiting factors of primary productivity? dioxide, water and mineral nutrients. Deficiency of any of these can limit photosynthesis or primary production.
What are the two most important factors in determining the level of primary productivity in an aquatic ecosystem? In aquatic ecosystems, primary productivity depends on nutrient availability and light, and to a lesser extent on temperature and other factors.
What are the two main factors influencing primary production? We focus on two main variables – light and nutrients – and their role in determining primary production.
Which of the following is the largest ecosystem in the world?
The world ocean is the largest existing ecosystem on our planet. See the article : What is productivity. It covers more than 71% of the earth’s surface and is a source of livelihood for more than 3 billion people.
Which Brainly is considered to be the largest ecosystem in the world? Explanation: The biosphere is the largest ecosystem on Earth.
Is the hydrosphere the largest ecosystem? The largest ecosystem on Earth is the aquatic ecosystem or hydrosphere. Aquatic ecosystems include lakes, rivers, oceans, streams, and other wetlands. Explore more such questions and answers at BYJU’S.
Why is productivity less in aquatic ecosystems?
In aquatic ecosystems, productivity is limited by light, which decreases with increasing water depth. On the same subject : How to find productivity.
Why does the ocean have low net primary productivity? The average ocean nuclear power plant is so low because the amount of ocean (mostly open space) is large compared to the amount of producers.
Which aquatic ecosystem has the lowest productivity? So the correct option is “Open Ocean”. in the aquatic ecosystem, net primary productivity is related to. Food chains and food webs.
Why is productivity in the oceans low? In the ocean, sunlight is the main limiting factor that reduces the rate of photosynthesis. … Minerals and nutrients can also be a deterrent depending on the location of the oceans, so productivity will be lower than the earth’s 170 billion tons compared to 55 billion tons of ionic oceans.
What is the primary productivity of an ecosystem?
Primary productivity in ecology is the rate at which photosynthetic producers (photoautotrophs) are converted into organic matter, which produces energy and nutrients through sunlight, and chemosynthetic producers (chemoautotrophs), which obtain chemical energy through oxidation. See the article : How to pronounce productivity.
What is primary production in an ecosystem? Definition of primary production: The process of assimilation and fixation of inorganic carbon and other inorganic nutrients into organic matter by autotrophs is called primary production. In calculations of primary ecosystem production, the chemical energy source is usually omitted.
What is the primary productivity of an ecosystem and how is it expressed? NPP = GPP – R. (a) Primary productivity is defined as the amount of biomass or organic matter that plants produce per unit area during photosynthesis over a period of time. It is expressed in the form of weight (g-2) or energy (kcal m-2).
Which aquatic ecosystem has the highest productivity?
In the aquatic ecosystem, coral reefs show the highest gross primary productivity. On the same subject : How productivity can be increased. A large number of aquatic phototrophs and phytoplankton contribute to ecosystem productivity.
Which ecosystem has the highest 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.
What is the productivity of the aquatic ecosystem? In aquatic ecosystems, primary productivity depends on nutrient availability and light, and to a lesser extent on temperature and other factors. Primary productivity is important because the process is that basis of food webs in most ecosystems.
What is responsible for low productivity of aquatic habitat?
These factors include the availability of essential inorganic nutrients, especially nitrogen and phosphorus; water temperature; and water turbidity. To see also : How to calculate productivity percentage. Open oceans have relatively low primary productivity due to low levels of essential nutrients nitrogen and phosphorus.
What factors affect the productivity of the aquatic ecosystem? Temperature and dissolved oxygen levels are among the factors that affect productivity. Overall, the predominance of Bacillariophyceae in the lake plays an important role in productivity, accounting for more than 65% of total phytoplankton numbers during the study period.
What is the main reason for low ocean productivity? Decreased photosynthesis reduces the growth of aquatic plants and animals. Minerals and nutrients can also be a deterrent depending on the location of the oceans, so productivity will be lower than the earth’s 170 billion tonnes compared to 55 billion tonnes of ionic oceans.
