在热带海洋环境中,红树林是具有较高生产力的生态系统。通常认为,红树林湿地区域可为毗连的沿岸水域和相关的生物群落生境提供有机物和无机物。尽管在红树林区域中具有很高的生产率,但红树林的树木一般是生长在营养比较贫瘠的热带地区。在红树林湿地的生境中,常见的蓝藻细菌通常起着对大气中的氮进行固化的重要作用。其他的固氮的生物但属于异养的真细菌,通常都存在于海水的沉淀物中,也起着大大有助于固定氮输入的持续供应作用。此外, In tropical marine environments, mangroves are ecosystems with higher productivity. It is generally accepted that mangrove wetland areas provide organic and inorganic supplies to contiguous coastal waters and related biome habitat. Despite their high productivity in mangrove areas, mangrove trees are generally grown in tropical areas where nutrition is poor. In the habitat of mangrove wetlands, common cyanobacteria bacteria often play an important role in the solidification of atmospheric nitrogen. Other nitrogen-fixing organisms, but heterotrophic eubacteria, are commonly found in sediments of seawater and also serve as a persistent supply that greatly contributes to the fixation of nitrogen inputs. In addition,
