Ultraviolet (UV) light is an electromagnetic radiation with a wavelength from 400 nm to 100 nm, shorter than that of visible light but longer than X-rays.V radiation is present in sunlight, and is produced by electric arcs and specialized lights such as mercury-vapor lamps, tanning lamps, and black lights. Although lacking the energy to ionize atoms, long-wavelength ultraviolet radiation can cause chemical reactions, and causes many substances to glow or fluoresce.
A terrestrial ecosystem is a type of ecosystem found only on biomes also known as beds. Six primary terrestrial ecosystems exist: tundra, taiga, temperate deciduous forest, tropical rain forest, grassland and desert. A community of organisms and their environment that occurs on the land masses of continents and islands.
An ecosystem refers to all the living organisms and their non-living environment within a given area. Note that this definition includes two. components; the living component which consists of the animals, plants and microbes, and the non-living component which refers to the air, water, rocks, soil and weather.There is no limit to how large or small an ecosystem can be. An ecosystem can be as large as an ocean or as small as a puddle.Very large ecosystems are known as biomes. An important point to recognize about ecosystems is the interaction between a grouping of plants and animals and their non-living environment and how the two strive to achieve a balance.omponents; the living component which consists of the animals, plants and microbes, and the non-living component which refers to the air, water, rocks, soil and weather.
