Which of these ecosystems has the highest primary productivity per square meter?
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 the following 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? Oceans contain greater concentrations of nutrients compared to other ecosystems. Oceans receive a greater amount of solar energy per unit area.
Which ecosystem has the highest net primary productivity per unit area quizlet?
What ecosystems are the most productive in the world? The open ocean and tropical/temperate rain forests.
Which of the following terrestrial ecosystem has the highest rate of 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.
What is high net primary productivity?
The primary productivity of an ecosystem is defined as the speed at which the solar energy is turned into an organic substance by chlorophyll in the photosynthesis. … A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable.
Which type of aquatic ecosystem has the highest net primary productivity?
In the aquatic ecosystem, coral reefs show the highest gross primary productivity. Large numbers of aquatic phototrophs and phytoplankton contribute to the productivity of the ecosystem.
Which of the following would have the highest biomass in an ecosystem?
Explanation: In general, the higher the trophic level (increasingly apex predators), the lower the biomass. Therefore, the lowest trophic level has the greatest biomass, and those are the producers. These include things like grass, trees, and flowers.
Why is terrestrial productivity higher in equatorial climates?
Why is terrestrial productivity higher in equatorial climates? -Productivity increases with water availability. -Productivity increases with available sunlight. … Acid precipitation lowered the pH of soil in a terrestrial ecosystem that supported a diverse community of plants and animals.
Which aquatic ecosystem has the highest net primary productivity quizlet?
COLD AND DRY biomes have the highest net primary production. WEATHER describes the average conditions, including temperature and precipitation, over long periods in a given area. Under water, photosynthesis by aquatic plants and phytoplankton is mostly limited by the amount of OXYGEN available.
Where is the GPP the highest?
The highest GPP values are in tropical regions (e.g. Amazonia, Central Africa and Southeast Asia) because of the wet and humid climate; and, the lowest GPP values are mainly in the arid regions of North Africa, West Asia and South America, as well as the cold and snow-covered regions (e.g. Greenland), due to the …
What biome has the lowest net primary productivity?
The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome. These biomes include habitats that have extreme temperatures and very limited precipitation, which results in very low production of new biomass.
