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 is comprised of all the non-living elements and living species in a specific local environment. Components of most ecosystems include water, air, sunlight, soil, plants, microorganisms, insects and animals.Ecosystems may be terrestrial -- that is, on land -- or aquatic.Sizes of ecosystems vary; they could entail a small puddle or an enormous swath of desert.esert Ecosystems. With a drier climate than grasslands, desert ecosystems are characterized by relatively sparse vegetation, and the number of insects and animals is also relatively limited. Deserts arenât necessarily hot; they can lie in temperate zones as well.
