Many abiotic factors affect the Temperate Deciduous Forest and the Tundra. There are more organisms found in the Temperate Deciduous forest than the Tundra due to its many abiotic factors.
The Tundra is a very dry biome. It receives very little precipitation about 10-12 cm per year. The Tundra supports very few organisms. It has a very short growing season, which limits the types of plants to survive. They must be capable of growing quickly, flowering, and seeding before the winter arrives. A very important mater that the plants must deal with is the layer of permafrost, the layer of soil that never thaws. The active layer, which is under the permafrost layer, is the active layer, which thaws in the summer. It helps give water and minerals to the plant roots. Due to the permafrost layer, large trees are unable to grow. The Tundra has very low temperature for most of the year. In the northern parts of the Tundra where the active layer is thinnest and air temperatures are most extreme, lichens and moss dominated. In the south, where the permafrost is weak, tall grasses, small shrubs, and even stunted coniferous trees grow. The Tundra doesn't lack water in the summer. The snowmelt, which cannot flow through the permafrost, is held in the active layer. Decomposition is really slow, the cold limit reproduction of soil bacteria and the growth of soil fungi. Few species live in the tundra like the Caribou it eats the lichen and moss. The lack of plant matter limits the number of organisms living in the Tundra Forest. .
The Temperate Deciduous forest Biome is a much warmer climate area, where it can support organisms in the three different layers. The precipitation is about 100 cm/a. The forest has a longer growing season, which deciduous trees such as maple and oak are able to grow. The Deciduous forest has high temperatures, which allow faster decomposition, and the organic matter available from fallen leaves provides the basis for formation of a richer soil.
Angiosperms are flowering plants. Angiosperms are the biggest group in the plant kingdom. ... Angiosperms are more highly evolved that the algae, mosses, fungi and ferns. ... Angiosperms are the primary food source for animals and provide oxygen for us to breathe. ... They are not like the angiosperms that have seeds contained flowers. ...
Gymnosperms and angiosperms are both seed plants. ... Angiosperms produce their megaspores by meiosis before their microspores. ... In angiosperms, however, daughter nuclei divide to form eight haploid nuclei. ... It only takes angiosperms' pollen tubes several hours to form. ... Angiosperms also form endosperm from the merging of sperm and polar nuclei. ...
Flowers are also the reproductive structure of flowering plant aka an angiosperm. In most angiosperms, insects and other animals transfer pollen from to another flower's female sex organs. ... Numerous floral variations evolved during the hundreds of million years of angiosperm history. ...
The Cenozoic Era marked the end of the dinosaurs and the emergence of mammals and birds. Although primitive mammals and birds first appeared in the Mesozoic era, it was not until the Cenozoic Era that they really emerged as powers in the world.

Flowers and Evolution In his work "How Flowers Changed the World", Loren Eiseley describes the importance of flowers and how they contributed to the evolution of animals, as well as to the emergence of mankind. Millions of years ago, before flowers bloomed across the earth, the landsc...
Aloe Vera Aloe Vera is a member of the Liliaceae family. Also known as Aloe barbadensis, Barbados aloe, and medicinal aloe. (Quattrocchi, 2000) There are nearly five hundred species of aloe, found throughout the world today. These low or stem-less plants that originated from Africa, have prickly...
He then proceeds to point out that the theory of the dinosaurs overdosing on angiosperms was mainly speculation because these plants were around for at least 10 million years before the mass extinction of dinosaurs occurred and there is simply no way to prove that these plants caused an overdose that killed even one dinosaur not to mention all of them. ...

The term bryophyte is used to describe a phylum of plants that are composed of over 25,000 species throughout the world. Bryophytes are made up of three major groups of plants: the mosses, liverworts, and hornworts, all of which are located throughout the world, even in extreme environments ( Rave...
The cannabis plant is a globally growing angiosperm. Many varieties of the cannabis plant exist. The variety of the plant is determined by the percent content of its chemical constituents. All varieties of cannabis plants contain a class of molecules unique to its genus, these are referred to as ...
