Similarly, once the sun sets in a desert, the warmth is quickly radiated away into the atmosphere as there are no clouds to trap it. These areas lying beyond the tree line comprise more than 10 percent of the Earths land surface. The dry, barren stems become plump with moisture, lush leaves appear, and bright crimson flowers bloom. After flowering, cactus fruits appear and persist on the desert plant for several months. The old man cactus is a large plant with multiple cylindrical thorny stems forming a large shrub. At that time their seeds quickly germinate, and the plants develop flower, and produce new seeds, which Large white trumpet-like flowers attract pollinators such as honeybees and hummingbirds. It is unsuitable for bows, spears, or boat building; for these purposes the Inuit either had to travel to the tree line or search for driftwood, which was formerly widely distributed along the Arctic coasts. When defining biomes it is important to look at vegetation, and a polar ice cap region is normally a place that has very little vegetation, consisting of small shrubs, herbs and lichens mostly, and definitely lacks trees and large shrubs. Unlike the tundra that can support plant and animal life in the summer . The tundra is characterized by permafrost, a layer of soil and partially decomposed organic matter that is frozen year-round. Thinning of the ozone layer in the polar regions resulting from the industrial release of chlorofluorocarbons into the atmosphere may have long-term consequences for plant and animal life. However, most deserts do receive rain, even if only for a few days each year. Many fungi reproduce with fruiting bodies, a spore-bearing structure produced above soil or a food source.

Other significant factors that have hampered terrestrial biotic evolution are the harsh climate, the ice cover that completely engulfed the continent during the Pleistocene glaciations, and the present limited number of ice-free land areas, which are restricted primarily to the coastal fringes and nunataks (mountain peaks surrounded by the ice cap). Through this process, plants capture the suns energy and use it to fuel chemical reactions that convert carbon dioxide and water into oxygen and energy-containing carbohydrates (sucrose, glucose, or starch).
