Quick Answer: Which of the following has highest biomass in aquatic ecosystem?

Which one is the reason for highest biomass in aquatic ecosystem?

Due to abundance of light, water, oxygen, carbon dioxide and less salanity of water, the tidal zone is characterized by exhorbitant growth of plants. The dense growth of vegetation, on the other hand, provides shelter and food for animals.

Which type of aquatic ecosystem is the most biodiversity?

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 trophic level has the highest biomass?

In this case, the trophic level which contains the greatest biomass is the producers, which is the lowest trophic level. This means that there are more producers than the first level consumers. Examples of producers include plants, algae, grasses, trees, and flowers.

What is ocean biomass?

In the world oceans there is large amount of biomass suspended in the photic zone of water column. Part of the living part is of plant origin, the phytoplankton and other is the animal component or zooplankton. There is also large proportion of particulate organic matter composed by remains of dead animals and feces.

What happens to most energy at each trophic level?

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

What is the dominant second trophic level in a lake ecosystem?

Correct answer: So, the correct answer is Zooplankton.

What are the 4 aquatic ecosystems?

Wetlands, rivers, lakes, and coastal estuaries are all aquatic ecosystems—critical elements of Earth’s dynamic processes and essential to human economies and health. Wetlands connect land and water, serving as natural filters, reducing pollution, controlling floods, and acting as nurseries for many aquatic species.

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.

What are the 7 aquatic ecosystems?

Aquatic ecosystems include oceans, lakes, rivers, streams, estuaries, and wetlands. Within these aquatic ecosystems are living things that depend on the water for survival, such as fish, plants, and microorganisms. These ecosystems are very fragile and can be easily disturbed by pollution.

Where is the most aquatic biodiversity?

Aquatic biodiversity is greatest in tropical latitudes. For example, an estimated 3,000 species of fish are found in the Amazon River alone. Coral reef habitats also have extremely high biodiversity; nearly a quarter of all known marine species are found in coral reefs.

What is high biodiversity?

High biodiversity is a habitat or ecosystem that has a high number of different species.

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.
