Wetlands and Mangroves Quiz

Which of the following is a way to potentially eliminate one of the greatest threats to the world's mangrove wetlands?

• increase desalination to reduce the effects of prolonged drought in mangroves

• integrate ecologically sound shrimp aquaculture practices with mangrove management

• construct dams in mangroves to increase sediment load and decrease pollution

• employ irrigation methods to address potential desertification of mangrove habitats

Which of the following is most likely to result from destruction of wetlands surrounding a river?

• a decreased sediment load in the river

• a decreased level of pollutants such as nitrates in the river

• an increased diversity of aquatic species in the river

• an increased level of oxygen in the river

• e. an increased frequency of flooding of the river valley

Which of the following approaches would best decrease the impact of frequent flooding in a community that is subject to the hazard of flooding?

• Construct wetland areas near the rivers and streams.

• Remove forested areas around all streams and rivers and change land use to agriculture.

• Increase the height of natural levees downstream from the community.

• Encourage developers to build housing developments on the floodplain.

What is a Wetland?

• Areas where water covers soil and doesn't drain either all year or certain times

• Areas where soil covers water all year

• Similar to a tsunami; giant waves caused by natural disasters

• An area where water isn't present for a long time to the point it looks like a desert

Which of the following statements best describes how the Clean Water Act legislation aims to protect wetlands from being lost?

• The Clean Water Act bans the draining of wetlands over five acres in size.

• The Clean Water Act requires wetlands to be constructed to mitigate the effect of newly drained wetlands.

• The Clean Water Act establishes standards for the quality of surface waters that must be continually monitored and reported.

• The Clean Water Act prohibits the use of wetlands for development and construction.

What is a Mangrove?

• A descendant from the lion species and are very similar in looks except they are herbivores

• Tropical plants that usually reside in tropical areas but are heavily declining in numbers due to loose, wet soils, salt water, and being submerged

• An herbivore that is descended from the koala and reside in warmer climates

• Tropical plants that reside near the coast which can tolerate loose, wet soils, salt water and being submerged

How is human development a threat to wetlands?

• As humans continue to build and develop buildings it will allow biodiversity to increase in cities and human populations and wetlands will be deserted

• As humans continue to build and develop buildings it allows animal populations to blend among humans leaving the wetlands all alone

• As humans construct buildings this can lead to changes in water quality, flow rates, and pollutant inputs

• As humans build for development it increases the amount of fertilizer runoff that goes into the wetlands

How are fish impacted in wetlands?

• The fish species increase because there is huge amounts of water in wetlands

• Lots of fishermen will find these spots attractive and overfish in these areas

• Lots of fish will compete with each other within wetlands because they like this area and don't wanna share

• Fish depend on these wetlands, wetlands serve as a food base, shelter, spawning and nursery areas, and for water filtration.

What Climates do Mangroves reside in?

• Tropical

• Semi-Arid

• Arid

• Dry

Recall The National Everglades Park case study, what is one way the wetlands negatively impacted the water surrounding it?

• Lots of oxygen accumulated within the wetland and caused soil degradation

• The Declining of wetland populations has disrupted the ecosystem and its services

• The enormous amount of phosphorus that has accumulated within the wetland has degraded the water quality

• Algae bloom has increased
