In marine waters the most productive systems are brown algal beds, seagrass beds and coral reefs. The kelps, brown algae of the genera Laminaria and Macrocystis, form dense forests in the sublittoral zone of rocky coasts in cool waters.
Are aquatic ecosystems productive?
Primary productivity is the conversion of the sun’s energy into organic material through photosynthesis. … In aquatic ecosystems, primary productivity is driven by the availability of nutrients and light and, to a lesser extent, by temperature and other factors.
Which of the following marine ecosystem is the most productive one?
The answer is coral reef ecosystem .
Which aquatic biome is the most productive and why?
These highly productive areas have an average annual net primary production of over 1,000 grams per square meter per year. The aquatic biome with the highest level of primary productivity is the coral reef biome with around 2,500 grams of biomass per square meter per year.
Are aquatic and marine ecosystems the same?
Marine ecosystems are aquatic environments with high levels of dissolved salt, such as those found in or near the ocean. Marine ecosystems are defined by their unique biotic (living) and abiotic (nonliving) factors.
Which ecosystem is the most productive?
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).
What is the most productive type of aquatic ecosystem?
It is thus not surprising that the most productive natural aquatic plant communities are benthic. In marine waters the most productive systems are brown algal beds, seagrass beds and coral reefs.
What are the two most productive aquatic ecosystems?
List two of the most productive ecosystems or aquatic life zones and two of the least productive. The two most productive are estuaries, swamps and marshes, and tropical rain forests. The two least productive are open ocean, tundra, and desert.
Which part of the ocean is 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.
What is the productivity of aquatic ecosystem?
The productivity of aquatic systems has been given two meanings in the literature: either the transfer of matter or energy through the food web, or the quantity of fish that may be captured in a sustainable way per unit of time.
What is the most productive type of aquatic ecosystem quizlet?
The most productive marine habitats are in the open ocean.
