And, as scientists are discovering, mangrove swamps are extremely important to our own well-being and to the health of the planet. . Mangrove ecosystem is a system consisting of biotic and abiotic environments that interact with each other in a mangrove habitat (Kusmana, 2002). Some organisms will eat the leaves directly, especially crabs and insects, while other decomposers wait for the mangrove leaves to fall to the ground and consume the decaying material. /Type /XObject /F3 29 0 R /Tabs /S /Group << /MediaBox [0 0 612 792] The problem is that this approach doesnt work very well.
