浮游生物的生长和他们得到的阳光以及重要的营养元素铁元素等相关。
The growth of phytoplankton is kept in check by the amount of sunlight available for photosynthesis and the supply of crucial nutrients such as iron.
莫顿解释说，厚厚的浒苔海藻潮将仅有的那么一点照进深海的阳光挡住，深海生物的世界完全黑暗。

电脑屏幕、iPad等发出的光线对生物钟的影响和太阳光差不多。
The light from a computer screen or an iPad has roughly the same effect as the sun.
海水的清晰度可被用作衡量在特定水域的浮游植物数量的指标，因为这些微生物生活在海洋表面，在那里它们可以得到它们用之产生能量的阳光。
That can be used as a proxy for phytoplankton population in a given area, since the tiny organisms live close to the ocean's surface, where they are exposed to sunlight they use to produce energy.
这种情况下，拉上你的窗帘那么阳光——它将调节你的生物钟——将不会在白天睡觉时候打扰你。
In this case, keep your window coverings closed so that sunlight - which adjusts your internal clock - doesn't interrupt your daytime sleep.
夏天带给我们阳光灿烂的日子、长满庄稼的田园和许许多多昆虫及野生生物，而冬天带给我们雨水、冰冻的道路和雪。
The summer brings us sunny days, fields full of crops and plenty of insects and wildlife, whereas the winter brings us rain, icy roads and snow.
泉水上部的石块被绿色生物膜覆盖，它通过阳光和硫化物自然的发生化学反应生存。
The top of the springs' rocks are covered with green biofilms, which use both sunlight and sulfide-naturally occurring chemicals from the springs-to survive.
琼斯和他的同事们还想研究混合营养体与光养生物或依赖阳光生长的生物共同生长时的表现。
However, Jones and her colleagues also wanted to see how mixotrophs fared when living together with phototrophs, or light-dependent organisms.
最近，菲戈罗进行了一项实验。她通过实验观察上午的阳光是如何影响中学生的生物钟的。
Recently, Figueiro ran an experiment to see how exposure to morning light affects the circadian clocks of middle school students.
生物进化选择了斐波那契布局帮助树木跟踪在天空中不断移动的太阳，让树木即使在最茂盛的森林中也能尽量多地收集阳光。
Evolution chose the Fibonacci pattern to help trees track the sun moving in the sky and to collect the most sunlight even in the thickest forest.
它们消耗其他生物体或有机物的能力帮助它们在阳光加强后迅速恢复生长，这种状况与灰尘碎片飘落后阳光加强后的情况可能极为相似。
Their ability to consume other organisms or organic matter helped them rebound quickly after low light returned, perhaps similar to the clouds of dust and debris finally beginning to clear.
研究人员依然能够分析几乎每一滴水、每一瓦特阳光，能够追踪碳氧流量以及监测每一种生物体。
Researchers can still account for nearly every drop of water and watt of sunlight, track parts-per-billion flows of carbon and oxygen, and monitor every organism.
论文的作者希望进一步研究并揭示所谓的太阳光促使维生素合成的生物理论。
The authors of the study agreed that the issue requires further study to shed light on the biological basis of the so-called sunshine vitamin.
坚持按时睡觉和起床能帮助你保持和自己的生物钟同步，生物钟是受阳光影响的24小时的内在节奏。
