Mangrove Swamp - Exploring Nature While most tiger species avoid humans, this tiger is notorious for actively hunting humans, a trait that has earned it the name man eater. Although for a time, fear of the creatures and the inaccessibility of their chosen habitat protected the tigers from human poaching, recent sea level rise is now threatening their existence. Mudskippers are fish that spend the majority of their time out of water, and some can even use their powerful pectoral fins to climb trees. For many mangroves, however, the salt is dealt with after it enters the plant. /Font << Life by the ocean has its perksfor mangroves, proximity to the waves and tides helps with reproduction.

BSM-4109: Project Preparation WSC A spectacled caiman patrols a salty pond at a Smithsonian research station in Panama. The biggest threat to mangroves is the emergence of shrimp farms, which have caused at least 35 percent of the overall loss of mangrove forests. Decomposer Definition A decomposer is an organism that decomposes, or breaks down, organic material such as the remains of dead organisms. A mangrove is a woody tree or shrub that lives along sheltered coastlines within the tropic or subtropic latitudes. They protect the climate by absorbing carbon dioxide and reducing the amount of greenhouse gases in the atmosphere. Mangroves categorized as secretors, including species in the black mangrove genus Avicennia, push salt from the ocean water out through special pores or salt glands within their leaves. Mangrove ecosystems are some of the most productive in the world.
