1. What is a mangrove forest?

forest comprised of low-level pine trees
forest comprised of scrubby plants
forest comprised of tall hardwood trees
forest comprised of hardy, salt-tolerant trees

4. Mangroves control salt intake

with membranes in root cells that keep out salt.
by secreting salt with special leaf glands.
by storing it in leaves until the leaves die.
all of the above

9. Crabs are a common part of the mangrove ecosystem with over 60 species found. One very recognizable species has a large claw that it waves around to attract mates. What crab is this?

mud crab
mangrove crab
fiddler crab
leaf-eater crab

10. Mangroves are important ecosystems because
they prevent coastal erosion.
they trap sediments.
they trap excess nutrients from agricultural runoff.
all of the above.

Mangroves are small trees and shrubs that live in the coastal zone. Mangrove trees must fight rough tides, huge waves, strong winds, and storms, as well as salt in the surrounding.

Q4: The answer is by secreting salt with special leaf glands.

When levels of salt are high, mangroves use leaf glands that can be found on the back of the leaf. That way they excrete an excess of salt.

Q9. The answer is fiddler crab

Fiddler crabs are semiterrestrial and usually, live along sea beaches. They can be found in mangroves and in muddy or sandy beaches.

Q10. The answer is all of the above.
