decomposers
分解： 由分解者（主要是細菌）的分解有機化合物的屍體及廢物的水生生物到簡單的營養成分，供水產品生產者。大部分分解者屬於異營性生物，無法從自行產生能量自 養，必須靠攝食來取得能量，而它的攝食方式，則是生物體本身釋放酵素到環境中分解有機物，吸收自己要的養分以生存，當該有機物被分解者分解後，會變成無機 物，重新回到生態系統中給生產者(利用無機物生存)使用，這類生物如：異營性細菌(自營性細菌除外)、菌物界中的生物，部分原生動物及原生菌類。

coevolution 共同演化
生物因受環境或需求的影響，親緣性遠的不同種生物可能衍生類似功能的構造，因適應而推演成不同種類。另外，生物與生物之間也會因互動而有互相適應的構造或行為衍生，此稱為共同演化。

Wind also has a downside. Wind-blown dust storms in the Sahara Desert have increased tenfold since 1950 mostly because of drought due to climate change, and human population growth. Another reason is the SUV connection. Increasing numbers of four-wheel vehicles speeding over the sand break the desert’s surface crust. Wind storms can then blow the dusty material into the atmosphere.風也有缺點。在撒哈拉大沙漠沙塵暴已經增加了十倍自1950年以來，主要是因為乾旱因氣候變化和人類人口的增長。另一個原因是越野車的連接。越來越多的汽車，加速沙子的增長，打破了沙漠表面的地殼。風就會使塵土飛揚於大氣中。Wind also transports harmful substances. Particles of reddish-brown soil and pesticides banned in the United States are blown from Africa’s deserts and eroding farmlands into the sky over the U.S. state of Florida. Some types of fungi in this dust may play a role in degrading or killing coral reefs in the Florida Keys and in the Caribbean.風也有害物質的運輸。紅褐色的土壤和農藥在美國是被禁止的，來自非洲的沙漠和侵蝕的農田進入美國佛羅里達州的上空。有些種類的真菌在這灰塵可發揮作用或殺害珊瑚礁在佛羅里達群島和加勒比地區。Particles of iron-rich dust from Africa that enhance the productivity of algae have been linked to outbreaks of toxic algal blooms-referred to as red tides-in Florida’s coastal water. People who eat shellfish contaminated by a toxin produced in red tides can become paralyzed or even die. These red tides can also cause fish kills.來自非洲的塵土，粒子富含鐵，提高藻類生產力，和產生有毒的赤潮，被稱為赤潮。在佛羅里達州的沿岸水域，人們誰吃了被污染毒素的貝類會使人成為癱瘓，甚至死亡。這些赤潮也可能造成魚類死亡。
