Question: Which of the following terrestrial ecosystems has the highest rate of primary productivity?

Which of the following ecosystems has the greatest primary productivity per area?

The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.

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 terrestrial ecosystem is considered the most productive on earth?

Tropical forests tend to be much more productive than other terrestrial ecosystems, with temperate forests, tropical savannah, croplands, and boreal forests all exhibiting middle levels of primary production (Table 1).

Which of the following biomes are more productive in terms of net primary productivity?

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 ecosystem has the highest productivity?

In terrestrial ecosystems, tropical rainforests have the highest productivity.

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 biome would have the highest net primary?

Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes. Net primary productivity ranges from 2–3 kg m2 y1 or higher.

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 of these ecosystems has the highest net 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).

What is high 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.

Why are marshes the most productive?

Low or intertidal marshes are more productive than high marshes because of the increased exposure to tidal flow. … If you look at a salt marsh it has full sun, limitless water, and the sedimentary soil is generally rich in nutrients so you’d expect uniformly high production.

Why does the tropical rainforest have the highest net primary productivity?

In Tropical Rainforests, water, sunlight, and high temperatures are consistent and a dense concentration of plants is present, causing both the GPP and NPP to be very high. So, high levels of productivity increase biomass.

Which biome is the most productive quizlet?

Which biome is the most productive? Tropical wet forest; the abundance of water and warmth make these the most productive environment.
