What is the most productive aquatic biome?
The answer is coral reef ecosystem . More than 25% of marine flora and fauna live in this ecosystem, but corals occupy only 1% of the ocean floor.
What biomes are the most productive?
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 are the two most productive biomes?
There are also two temperate biomes that have high levels of primary productivity, the temperate evergreen forest biome and the temperate deciduous forest biome. Although these biomes produce a large amount of biodiversity, they are limited by colder winters and less rainfall.
What is the least productive aquatic biome?
Oligotrophic lakes Lakes and Ponds Lakes are generally larger than ponds. Lakes are classified by how productive they are. Oligotrophic lakes have low levels of nitrogen and phosphorus and are the least productive.
What is 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 are productive biomes?
Several biomes, including tropical savannas, boreal forests, and temperate grasslands have moderate levels of primary productivity due to less precipitation and varying temperatures. The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.
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.
What are the most and least productive biomes?
Globally, patterns of primary productivity vary both spatially and temporally. The least productive ecosystems are those limited by heat energy and water like the deserts and the polar tundra. The most productive ecosystems are systems with high temperatures, plenty of water and lots of available soil nitrogen.
Why are estuaries very productive ecosystems?
Estuaries are very biologically productive. The salinity gradient and the changes in tides, fresh water and accompanying flux in nutrients within estuaries create a variety of habitats that support a diverse food web.
What are the aquatic biomes?
The aquatic biome can be broken down into two basic areas, freshwater (i.e, ponds and rivers) and marine (i.e, oceans and estuaries). The only thing that links all the areas together is that there is water.
Where are the most productive waters?
the oceans 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 are the most productive marine ecosystems?
Seagrass meadows Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world. They provide habitats and food for a diversity of marine life comparable to coral reefs.
What is the least productive biome?
The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.
Why tropical rainforest is the most productive ecosystem on earth?
Tropical Rainforests support the greatest number of species compared to any other biome on the planet. The high species diversity is brought about by warm temperatures and year-round rainfall – the average yearly rainfall is 100 inches – that ultimately allow for optimal growth.
Which of the following would be considered among the most productive ecosystems *?
Which of the following terrestrial ecosystems is most productive? Tropical rain forests with their warm wet conditions are the most productive of all terrestrial ecosystems.
Which of the following biomes are more productive in terms of net primary productivity?
tropical rainforest biome 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.
What is a productive biome?
The most productive ecosystems are systems with high temperatures, plenty of water and lots of available soil nitrogen. Adapted from source. Define 'Net Primary Productivity' Define 'productive biome'
What ecosystems are most productive?
Tropical rainforests show the highest productivity in terrestrial ecosystems.
Are estuaries most productive?
Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
What are the two main aquatic biomes?
The aquatic biome is the largest of all the biomes, covering about 75 percent of Earth's surface. This biome is usually divided into two categories: freshwater and marine.
What are the major aquatic biomes on Earth?
The 8 aquatic biomes are lakes and ponds, rivers and seas, oceans, estuaries, coral reefs, wetlands, mangroves, and intertidal zones.
Why estuaries is the most productive ecosystem?
Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
What is a productive aquatic ecosystem?
The most productive aquatic ecosystems are shallow-water marine ecosystems where light is ample and autotrophs are multicellular with complex structures or associations (e.g., corals and kelp). From: Fundamentals of Ecosystem Science, 2013.
Is deep Sea most productive ecosystem?
-Oceans contain lots of nutrients but they have no sufficient sunlight reaching in the deep areas, therefore, oceans have the least productivity among all ecosystems.
Which ecosystem is most productive?
Tropical rainforests Tropical rainforests show the highest productivity in terrestrial ecosystems.
What are the three most productive ecosystems?
The most productive ecosystems are fertile estuaries and marshes, coral reefs, terrestrial vegetation on moist alluvial deposits, and intensive agriculture, which can have productivities of 10-25 × 103 kcal/m2/yr.
Why are tropical wet forest and estuaries most productive?
Tropical Rainforests have high primary productivity because of availability of plenty of solar light and water. A typical estuary has high primary productivity because it is shallow (gets plenty of sunlight) and has turbulent water (which brings the nutrient rich material from sea bed).
Which of the following aquatic ecosystems has the highest net primary productivity?
In an aquatic ecosystem, coral reefs have the highest net primary productivity. It experiences a high photosynthesis rate due to the high light intensity in such an ecosystem.
Which is highest productivity?
Below are the ten most productive countries and their average work weeks.

Are estuaries the most productive ecosystems on earth?
Estuaries are among the most productive environments on earth. 4 times more productive in plant matter than a rye grass pasture and 20 times more productive than the open sea. Extremely rich in organic matter and nutrients. Photosynthesis occurs throughout the water column and on the sediment surface – very productive.
