The word is derived from the Greek scotos, σκότος, "dark," and relates to photobiology, which describes the biological effects of light (φῶς, phos; root: φωτ-, phot-). The term scotobiology appears not to have been used previously, although related terms such as skototropism [ 4 ] and scotophyle [ 5 ] have appeared in the literature.
Electric power systems consist of generation plants of different energy sources, transmission networks, and distribution lines. Each of these components can have environmental impacts at multiple stages of their development and use including in their construction, during the generation of electricity , and in their decommissioning and disposal.
Light is the food of plants, i.e. the form of energy that plants use to build themselves and reproduce. The organs harvesting light in plants are leaves and the process through which light is converted into biomass is photosynthesis. The response of photosynthesis to light is called light response curve of net photosynthesis . The shape is ...
The photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light. It is a physical phenomenon. [1] The photovoltaic effect is closely related to the photoelectric effect. For both phenomena, light is absorbed, causing excitation of an electron or other charge carrier to a higher-energy
Ecological light pollution [1] is the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.. The effect that artificial light has upon organisms is highly variable, [2] and ranges from beneficial (e.g. increased ability for predator species to observe prey) to immediately fatal (e.g. moths that are attracted to incandescent lanterns and are killed by ...
A mysterious light has been blinking in space every 21 minutes for 35 years–and scientists have no idea what it is. What could it be?

Of the 150 kWh falling on the crown, 1% is used for photosynthesis, 10% reflected as light energy, 5 to 10% as sensible heat with the remaining 79 to 84% entering the process of transpiration. [ 3 ] If a larger tree has a sufficient water supply, it can evaporate more than 100 L of water a day.
