Mangrove forests provide habitat for many marine and terrestrial species. These intertidal zone forests support the richest biological diversity and primary productivity and also support the livelihood of millions of people around the world, which is why mangrove considers an ecosystem of its own and has its own food chain. The mangrove food chain actually depends mainly on the recycling of debris, which comes from falling mangrove leaves, so the mangrove is the main producer of the mangrove food chain. This recycling is carried out by smaller organisms, such as snapping shrimps and burrowing crabs, with contributions from tube worms and bristle worms. These small organisms feed on the biomass of plants, which is why they are considered primary consumers of the mangrove food chain. One level above the level of detritus-feeding organisms is the smallest level of mangrove fish. These fish live and hide among the roots of mangroves. These fish are mostly sail-finned mollies, less killifish and mosquitofish. The level above the level of the smallest fish in the mangrove food chain is ...
