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.
Different Types of Ecosystems. There are essentially two kinds of ecosystems; Aquatic and Terrestrial. Any other sub-ecosystem falls under one of these two headings. Terrestrial ecosystems Terrestrial ecosystems can be found anywhere apart from heavily saturated places.he two main kinds of grasslands ecosystems are: 1  Savanna: The tropical grasslands are dry seasonally and have few individual trees. 2  They support a large number of predators and grazers. 3  Prairies: It is temperate grassland, completely devoid of large shrubs and trees.
