As the salty water evaporates, noticeable salt crystals often form on the surface of the leaves. Types of Decomposers There are two main kinds of decomposers, scavengers and decomposers. A mangrove forest is categorized into five types of forest-based upon its surrounding geography. An overwash forest is similar to a fringe forest except the entire forest is an island that becomes flooded at high tide. >> What Is the Role of Producers in an Ecosystem? | Sciencing << /A << Mangroves are a variety of species of broad-leaved trees (10-40 feet high) lying in muddy creeks and tidal estuaries. >> This slug caterpillar turns into a very plain brown moth with stinging spines. /F4 51 0 R /K [70 0 R 71 0 R 72 0 R 73 0 R 74 0 R 75 0 R 76 0 R 77 0 R 78 0 R 79 0 R HTMk@(Af%'( R[9wh+cy1`~,ua}{lWY]TeyS7y2E:OCH(B;>v=? /Type /Group /S /Transparency >> (1991) Fungal diseases in mangrove forest ecosystem.
