Question

Which ecosystem has the greatest biodiversity?

Question 15 options:

bog

estuary

marsh

swamp

Answer 1

Among the given ecosystems of bog, estuary, marsh, and swamp, the estuary has the greatest biodiversity due to the mixture of fresh and saltwater creating a diverse habitat for many species.

Step-by-step explanation:

The ecosystem with the greatest biodiversity is typically an estuary. Estuaries are areas where freshwater from rivers meets and mixes with saltwater from the ocean, creating a unique environment that supports a rich variety of life. These habitats serve as nourishing grounds for young crustaceans, mollusks, fishes, and many other species.

In comparison to the options given—bog, marsh, and swamp—estuaries offer a more dynamic environment with a higher degree of salinity and nutrient variation, leading to higher biodiversity. Wetlands, which include marshes and swamps, are also recognized for substantial biodiversity. They support plants such as mangroves, water lilies, cattails, and animals including various amphibians, reptiles, birds, insects, and mammals.

Answer 2

"Marsh" ecosystem has the "greatest biodiversity".

Option: C

Explanation:

Marsh or Wetland ecosystem is highlighted as “biological super systems” as it is responsible to manufacture giant volume of meal that favors large amount of biodiversity, which is rich as rain forests and local reefs. The combination of important nutrients, shallow water and large primary productivity is basic source for Earth's food web. For example such food web is supported by birds, shellfish, fish, amphibians and insects. This ecosystem helps filtration of pollutants and soil runoff from the upstream sources which in return support river, ocean and bays in cleaning downstream.
