In contrast, the matter in an ecosystem is continuously recycled as atoms are combined and recombined in different ways. Producers are organisms that create food from inorganic matter.

All mangroves have evolved special adaptations that enable them to live in salty, oxygen-poor soil.

These forests are dependent upon the regular tides that flush leaves, twigs, and mangrove propagules out into the open ocean. xiuF( Some species like Conocarpus erectus, the buttonwood, are often grouped with mangroves since they hug the upper edge of mangrove forests, however, they lack many of the characteristic adaptations of mangroves and are labeled mangrove associates.

As mangroves and seagrasses grow larger, they require more and more nutrients.

With only about 80 species of true mangrove trees worldwide, mangrove ecosystems comprise a relatively low number of habitat-forming tree species, but a high diversity of decomposer, detritivorous and consumer species. They raise the young in nurseries, taking turns caring for their own as well as others' offspring and protecting them fiercely. >> Its still unclear why these northern pioneers are so keen to start multiplying, but it may have to do with their genetics.

Miki T, Ushio M, Fukui S, Kondoh M (2010) Functional diversity of microbial decomposers facilitates plant coexistence in a plant-microbe-soil feedback model. After the shrimp reach maturitya time that takes between three to six monthsthe ponds are drained so the shrimp can be harvested, and toxic water that contains the shrimps waste, uneaten shrimp feed, pesticides, chemicals, and antibiotics is released into the surrounding environment where it can harm local ecosystems. In North America, they are found from the southern tip of Florida along the Gulf Coast to Texas. And in Hawaii. When those predators die, it is then up to the decomposers to hit the reset button on the food chain by harvesting nutrients that were passed from the producers to the consumers so they can be used again. Also, on some isolated tropical islands, such as Hawaii and Tahiti, mangroves are not native and are sometimes considered invasive species.
