[Mission 2024] STATIC QUIZ, 1 November 2023 – Environment

Solution: d)

The wetlands, vital parts of the hydrological cycle, are highly productive ecosystems which support rich biodiversity and provide a wide range of ecosystem services such as water storage, water purification, flood mitigation, erosion control, aquifer recharge, microclimate regulation, aesthetic enhancement of landscapes while simultaneously supporting many significant recreational, social and cultural activities, being part of our rich cultural heritage;

Solution: d)

The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of wetlands.

Solution: c)

Production/unit area depends on the number and diversity of producers.

Mangroves are one of the high productive regions in the world whereas ocean has least productivity.

Solution: b)

Statement 3 is incorrect.

Mangroves are a group of trees and shrubs, sustaining in the coastal regions of the planet. These trees grow in low-oxygen soil with slow-moving water. 

These ecosystems of tropical and subtropical inter-tidal regions bordering the sheltered sea coasts and estuaries, they stabilize the shoreline and act as a bulwark against encroachments by the sea. 

Solution: a)

Corals that inhabit the colder deep waters of continental shelves and offshore canyons, ranging from 50 to over 1000m depths lack zooxanthellae and may build reef-like structures or occur solitarily.

Cold-water corals are different from their warm-water counterparts because they do not contain symbiotic algae for photosynthesis and grow more slowly. Cold-water corals obtain all their energy from organic matter and zooplankton, which they catch from the currents drifting past.

Cold-water corals can be found over a wide range of latitudes, from tropical to Polar Regions, and from the shallow to the deep seas.
