Plankton浮游生物
Scattered through the ea of the world are billion of ton of mall plant and animal called plankton。 Mot of thee plant and animal are too mall for the human eye to ee。 They drift about lazily with the current, providing a baic food for many larger animal。
Plankton ha been decribed a the equivalent of the grae that grow on the dry land continent, and the comparion i an appropriate one。 In potential food value, however, plankton far outweigh that of the land grae。 One cientit ha etimated that while grae of the world produce about 49 billion ton of valuable carbohydrate each year, the ea' plankton generate more than twice a much。
Depite it enormou food potential, little effect wa made until recently to farm plankton a we farm grae on land。 Now marine cientit have at lat begun to tudy thi poibility, epecially a the ea' reource loom even more important a a mean of feeding an expanding world population。
No one yet ha eriouly uggeted that " plankton-burger" may oon become popular around the world。 A a poible farmed upplementary food ource, however, plankton i gaining coniderable interet among marine cientit。
One type of plankton that eem to have great harvet poibilitie i a tiny hrimp-like creature called krill。 Growing to two or three inche long, krill provide the major food for the great blue whale, the larget animal to ever inhabit the Earth。 Realizing that thi whale may grow to 100 feet and weigh 150 ton at maturity, it i not urpriing that each one devour more than one ton of krill daily。[由好作文www.hAOzuowEn.com整理]
分布在世界海洋的数十亿吨的小型动植物浮游生物要求。 大多数动植物太小,对人类的眼睛看到的。 他们飘流懒洋洋的潮流,提供了许多基本的食物大型动物。
浮游生物被称为草原相当于生长在干地上大陆,是比较恰当的。 粮食潜在价值,远远大于浮游生物的土地种植。 科学家估计,在全世界产生草约49亿吨,每年有价值的碳水化合物、海洋的浮游生物带来超过两倍。
尽管粮食的潜力巨大,已收到效果,直到最近我们浮游生物农场农场种植的土地。 现在海洋科学家终于开始研究这种可能性,特别是在海洋资源的机子更重要的,作为世界人口的温饱扩大。
但是没有人认真认为"浮游生物的一块"很快风行全世界。 作为补充食物来源可能耕种,人们的极大兴趣海洋浮游生物科学家。
一类浮游生物,似乎有很大的可能性是很小的收成虾一样东西称南极。 越来越两三英寸长,主要渔获为粮食大蓝鲸,最大的动物都生活在地球上。 实现这一鲸鱼可能增加到100英尺,重150吨,在成熟,这是不奇怪的,每个人的一吨多食海每日。
