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.
Ecosystems and Biomes. Ecosystem. An ecosystem is the living and non-living components of an environment and the interrelationships (connections) that exist between them.The non living components within an ecosystem are called the abiotic components, examples of abiotic components are the climate (sun light, rainfall) and rocks.iomes. A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region.
