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.
Classifying different environments: ecosystems and biomes. One way to group together areas that share characteristics is to look at the ecosystem of the area. An ecosystem is a group of living organisms interacting with the non-living parts of an environment.he harsh conditions of an extreme environment mean that only plants and animal species that have adapted are able to survive in the area. The vegetation, climate and soils are closely linked with one another. A large ecosystem is called a biome.
