Mangroves provide a _________________________for small fish before they swim out to the deeper ocean.

• Safe breeding ground

• Fresh water system

Why are mangroves important at a GLOBAL scale?

• Protect against tropical storms

• Carbon sinks

• Provide employment

• Tourism

Mangroves are adapted to saline environments through which of the following mechanisms?

• Excreting salt through their leaves

• Absorbing large amounts of freshwater to dilute the salt

• Growing extensive root systems to avoid salty water

• Developing thick, waxy leaves to reduce water loss

Mangroves contribute to the reduction of carbon emissions by:

• Releasing large amounts of carbon dioxide

• Storing carbon in their biomass and soil

• Increasing the acidity of the ocean

• Decreasing the oxygen levels in the atmosphere

What role do mangroves play in carbon sequestration?

• They release carbon dioxide into the atmosphere

• They store carbon in their biomass and in the soil

• They have no significant role in carbon sequestration

• They convert carbon dioxide into oxygen without storing carbon

How do mangroves contribute to the protection of coastal areas?

• By attracting tourist activities that boost local economies

• By reflecting sunlight and reducing sea surface temperature

• By absorbing wave energy and reducing erosion

• By increasing the salinity of coastal waters to deter erosion

Mangrove forests are crucial for the lifecycle of many marine species because they provide:

• Open ocean habitats

• Nesting sites for birds only

• A critical nursery habitat for fish and crustaceans

• High-altitude roosting spots

How do mangroves filter and purify water?

• By absorbing pollutants with their leaves

• Through the action of bacteria in the water

• By trapping sediments and pollutants in their root systems

• By evaporating contaminated water through their leaves

What is one of the main threats to mangrove ecosystems?

• Overfishing

• Deforestation for coastal development

• Increased rainfall

• Rising sea levels
