What freshwater ecosystem is the most productive?
Wetlands are among the most productive ecosystems in the world comparable to rain forests and coral reefs.
What ecosystems are most productive?
Tropical rainforests show the highest productivity in terrestrial ecosystems.
What aquatic ecosystems are most productive?
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.
Which freshwater ecosystem is least productive?
Answer and Explanation: The bog freshwater ecosystem is the least productive.
Why are estuaries 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.
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.
Which is highest productivity?
Below are the ten most productive countries and their average work weeks.
- Ireland. Ireland's productivity per hour is the highest of any country at $99.13. …
- Norway. Norway's productivity per hour is $80.83. …
- Switzerland. Switzerland is the third-most productive country. …
- Luxembourg. …
- Germany. …
- United States. …
- Denmark. …
- France.
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 effect do keystone species have on an ecosystem?
Role of Keystone Species in an Ecosystem A keystone species helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether.
How does high biodiversity affect an ecosystem?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
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.
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 are some of the most productive ecosystems on Earth Why?
Wetlands and Nature
- Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. …
- Wetlands play an integral role in the ecology of the watershed. …
- Wetlands' microbes, plants and wildlife are part of global cycles for water, nitrogen and sulfur.
Why are estuaries highly productive?
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.
Which ecosystem has least productivity?
So, the correct answer is 'Open oceans'.
What would happen if a keystone species was removed?
Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.
What are the 3 keystone species?
There are three types of keystone species cited by many scientists: predators, ecosystem engineers, and mutualists.
Which is more advantageous low or high biodiversity Why?
Answer and Explanation: High biodiversity is advantageous over low biodiversity because ecosystems with high biodiversity are better able to remain at homeostasis and be… See full answer below.
Which ecosystem has high biodiversity low biodiversity?
Estuarine areas (where rivers meet seas and oceans) have high biodiversity compared to other areas. Trophical rainforests are rich in terms of biodiversity. Arid and semiarid areas have low biodiversity. Deserts, for example, contain limited numbers of species.
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 two ecosystems on the planet 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).
Why are tropical wet forests 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 terrestrial ecosystem has the highest productivity?
Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.
What if beavers went extinct?
What Would Happen if Beavers Went Extinct? Since beavers have such an impact on the ecosystems they inhabit, the world would be a much different place without them. Some areas would become choked with too many trees, as there would no longer be the beavers to thin out the trees and create space for new trees.
What would happen if beavers were removed from Yellowstone?
In total, beavers are credited for enhancing bird diversity on three different continents. Without them, the forests would be less musical, and birding would be way more frustrating. That said, there are plenty of folks who still think beavers are a nuisance.
What is the most important keystone species for the planet Earth?
Bees have been declared the most important species on the planet, which comes as no surprise as they provide food and shelter to a humongous diversity of organisms. Bees make perfect examples of keystone species, they promote sustainability among ecosystems by cross-pollinating many different plant species.
Are humans a keystone species?
Ecologists have identified numerous keystone species, defined as organisms that have outsized ecological impacts relative to their biomass. Here we identify human beings as a higher-order or 'hyperkeystone' species that drives complex interaction chains by affecting other keystone actors across different habitats.
Which ecosystem has the highest biodiversity?
Coral reefs Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.
Which ecosystem has the highest diversity?
Coral reefs Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.
Which ecosystem has high levels of biodiversity?
Coral reefs are believed to have the greatest biodiversity.
