How mangrove can reduce soil erosion?
The leaves reduce transpiration
The leaves produce salt crystal
The roots hold the soil particle
The roots absorb more sea water
Mangrove swamps are important for______ the runoff water.
collecting
filtering
mixing
absorbing
How are mangroves helpful to people?
reduce the impact of waves and high winds
reducing erosion
creates carbon that is released into the atmosphere
mangroves are a good food source for people
Which of the following is NOT one of the benefits provided by a mangrove swamp?
Trap organic debris to keep the swamp full of vital nutrients.
Help to hold the sand and reduce erosion.
Accumulate partially decomposed organic matter to form peat.
Provide homes and shelter to numerous organisms.
How do mangroves help protect humans from hurricanes and tsunanis?
They release salt into the air, which neutralizes these events.
The birds, animals, and fish in the mangroves get killed instead of the humans.
They absorb up to 90% of the impact of these events.
This statement is false. Mangroves help cause hurricanes and tsunamis.
