【An ice floe which has keys to ecosystem has carried varied lives】

When the ice floe begins to melt in the first 10 days in March,a phenomenon happens.A large amount of phytoplankton 植物プランクトン are being released so much that the color of the sea changes as if it got cloudy.We call it spring bloom.😲

The phytoplankton is the important thing which supports the bottom of a food chain.The Amur River carries the land's nutritions with the water,and when the water is frozen,it becomes the ice floe.The ice floe includes plenty of the phytoplanktons.😃

A zooplankton 動物プランクトン eats the phytoplankton,the Crustacea 甲殻類 feeds the zooplankton,a comparatively bigger fish eats the zooplankton,and a sea animal feeds the fish.Lives continue to being connected one after another like that.😃

However,the ice floe shows us a tendency to decrease every year.Some specialists say influence of the ice floe is half as big as the one in 1 million years ago.😃
