夜间与昼夜
Biological organisms have biological clocks to facilitate them with the times to be active in order to fulfil their requirements. Usually, a day (24 hours) is the main temporal unit of biological species and the main times are the daytime and nighttime. Organisms could be divided into two main groups, based on the time that they are active, which are nocturnal and diurnal. There are many differences between nocturnal and diurnal organisms and the most important of those are discussed in this article.
Nocturnal
Nocturnal is an adjective that is used to describe the organisms that are active during the night. Usually, animals active in the night are described as nocturnal, but there are many plant species that show this behaviour too. The main obstacle for the nocturnal creatures is the lack of sunlight, and they have overcome the problem in such a way that the night being a blessing to fulfil their requirements. There are many改编exhibited by the nocturnal animals, to maximize the use of the nighttime.蝙蝠, owls, most of the serpents, manymammals, number of无脊椎动物,and a range of plant species can be brought out as examples for the nocturnal organisms.
The basic biological needs such as feeding and breeding activities are performed during the time an organism is active, which is the nighttime in this case. Apart from the lack of sunlight, the incidences of sounds are very low in the night. Therefore, nocturnal animals such as bats and owls take a great advantage of that opportunity by adapting with improved hearing and vocal systems. In fact, bats have a highly developed auditory system with a wide range of sensitive frequencies that easily exceeds the many audible frequencies of other animals including humans. Some of the insect species have developed light-emitting organ systems to overcome the obstacle of darkness. However, there are many organisms with developed adaptations for breeding in the night such asfrogsand plants. Usually, plants store energy viaphotosynthesis在白天，但在夜间开花，以吸引insects带有美妙的香水和颜色。理解夜间生物的适应性越多，它越揭示他们使世界成为生物生物的活跃场所。
Diurnal
当生物在白天保持活跃时，该生物被称为昼夜生物。白天的光和热量是有利于昼夜生物的主要身体状况。几乎所有的植物物种都是昼夜的，因为它们通过光合作用存储太阳能，只能在白天进行。由于植物是动物的主要能源（以食用食物的形式），因此许多动物也是昼夜的。许多reptilesand otherectothermic动物是昼夜，这有助于他们通过外部环境的热量维持体温。但是，尽管在白天进行了能量收集，但仍有许多夜间爬行动物。根据最有效的传粉媒介活跃的时间，植物选择昼夜或夜间活动。通常，大多数昆虫物种都是昼夜和有效的授粉媒介，大多数开花植物都选择昼夜以实现有效pollination. Since it is easy to spot and catch the prey species during daytime, most of the捕食者animals are diurnal. Additionally, most of the herbivorous animals are diurnal, which is mainly because of the fact that storage of generated food in plants via photosynthesis is taken away from the leaves during the night. There are umpteen examples to describe diurnal organisms with advantages of being so, and they make the vast majority of the biological creatures of the world.
夜间和昼夜有什么区别？
• Nocturnal is when an organism is active in the night, whereas diurnal is the opposite of that.
• There are much more diurnal organisms than the number of nocturnal species.
•很难比较昼夜动物和昼夜植物的数量，但是夜间动物的数量将高于夜间植物。
• Diurnal species advertise through colors and other visible parameters, whereas nocturnal species mainly depend on audible parameters.
