Readers ask: Where Is Year Round Marine Biological Productivity Greatest?

Higher chlorophyll concentrations and in general higher productivity are observed on the equator, along the coasts (especially eastern margins), and in the high latitude ocean (Figure 4a and b).

Which biological marine zone is the most energy productive?

When the water is relatively clear, photosynthesis can occur in the neritic zone. The water contains silt and is well-oxygenated, low in pressure, and stable in temperature. These factors all contribute to the neritic zone having the highest productivity and biodiversity of the ocean.

Which marine ecosystem has the highest 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 area of the coastal ocean has the highest primary productivity?

Inshore tropical waters have a productivity as much as 10 times higher than offshore because of high nutrients and light.

Which ecosystem is the most biologically productive?

Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

Where are the oceans most productive?

Although they occupy less than two percent of the oceans, the coastal upwelling areas in the eastern parts of the Pacific and Atlantic Ocean are among the biologically most productive marine areas worldwide.

Where is primary productivity in the ocean the greatest Why?

Higher chlorophyll concentrations and in general higher productivity are observed on the equator, along the coasts (especially eastern margins), and in the high latitude ocean (Figure 4a and b).

Where does all marine productivity begin?

Most marine primary production is generated by a diverse collection of marine microorganisms called algae and cyanobacteria. Together these form the principal primary producers at the base of the ocean food chain and produce half of the world’s oxygen.

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).

Where in the ocean is plankton productivity the greatest?

Where in the ocean is plankton productivity the greatest? Why? Salt marshes and groves have the highest plankton productivity because of the vast amount of nutrients in the environment.

Where is primary productivity highest?

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

Where in the ocean is productivity high at the surface Why?

In the fall as the surface waters cool off, they begin to mix with the waters beneath them, and this mixing, with the help of winter storms, stirs up nutrients. So the ocean is more productive in temperate zones. This also explains why the tropics have that pretty clear blue water. There’s not much life in it!

Which marine environment exhibits the greatest species diversity?

Since the majority of life thrives in warm and wet environments, biodiversity is greatest around the equator. Specifically, biodiversity of land species is greatest in tropical forests and marine diversity is greatest along coral reefs.

Which ecosystem most likely has the greatest biological diversity?

Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

Where is the world’s largest biological diversity found?

Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.

Quick Answer: How Are Biological Indicators Used In Environmental Science?

Bioindicators include biological processes, species, or communities and are used to assess the quality of the environment and how it changes over time. Bioindicator species effectively indicate the condition of the environment because of their moderate tolerance to environmental variability (Figure 1).
