Which ecosystem has the highest annual 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 type of ecosystem has the highest annual net primary productivity?

The tropical rainforest has highest annual net primary productivity (9000 K cal / m2 / yr).

Which of the ecosystems below has the highest 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 is high 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 of the following has highest net primary productivity?

The energy which is said to be stored at the producer level in an ecosystem is called primary productivity. In terms of per unit area per year, the highest value of the net primary of a forest ecosystem is highest in the tropical rainforest.

In terrestrial ecosystems, tropical rainforests have the highest productivity.

Which ecosystem would have the highest net primary production 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.

What is net primary productivity in 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.
