Which of the following ecosystem has the highest primary productivity?
Coral reefs ecosystem has the highest gross primary productivity.
Which of these terrestrial ecosystems has the highest net primary productivity?
Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes. Net primary productivity ranges from 2–3 kg m–2 y–1 or higher.
Which ecosystem would have the highest net primary production quizlet?
<Cold and dry> biomes have the highest net primary production. Water moves towards areas of <lower> salinity. Ecologists tend to divide the photic zone of lakes and ponds based on distance from the <bottom>.
Which type of ecosystem has highest annual net primary productivity per square meter per year?
The most productive ecosystems are the tropical rain forests with a dense and evergreen vegetation. It is productive throughout the year and has an annual net primary productivity of 9000 kcal per square metre per year.
What is high net primary productivity?
A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable. … The presence of some forms of secondary energy can also help to increase the primary productivity rate.
Which ecosystem has the highest primary productivity Mcq?
Tropical rainforests show the highest productivity in terrestrial ecosystems.
Which 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).
Which of these ecosystems has the highest net primary productivity per square meter annually 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? Oceans contain greater concentrations of nutrients compared to other ecosystems. Oceans receive a greater amount of solar energy per unit area.
Do cold and dry biomes have the highest net primary production?
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.
Why are gross primary production and net primary production not the same value?
Why are gross primary production and net primary production not the same value? Because primary producers use a portion of gross primary production to carry out their own life functions. What limits the net primary production in aquatic ecosystems such as lakes and streams? Available sunlight and nutrients.
