A certain biome is characterized by sedges, forbs, grasses, low-growing shrubs, lichens, and mosses. Its growing season is short, but summer days are very long. Although precipitation is low, the soil is often wet. Alternate freezing and thawing of soil results in a pattern of polygons and pingos on the soil surface. This biome is most likely

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

violet is number 1 in the chart of visible light.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
