Explain What is a Biome? : 

Explain What is a Biome? A biome mean-complex biotic community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region, esp. such a community that has developed to climax.

Desert Biomes : 

Desert Biomes Deserts cover about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Although most deserts, such as the Sahara of North Africa and the deserts of the southwestern U.S., Mexico, and Australia, occur at low latitudes, another kind of desert, cold deserts, occur in the basin and range area of Utah and Nevada and in parts of western Asia. Most deserts have a considerable amount of specialized vegetation, as well as specialized vertebrate and invertebrate animals. Soils often have abundant nutrients because they need only water to become very productive and have little or no organic matter. Disturbances are common in the form of occasional fires or cold weather, and sudden, infrequent, but intense rains that cause flooding.

Rainforest : 

Rainforest Forest Biomes represent the largest and most ecologically complex systems.  They contain a wide assortment of trees, plants, mammals, reptiles, amphibians, invertebrates, insects and micro-organisms which vary depending on the zone's climates.  Sadly, boreal and rainforest biomes are being cut down at an alarming rate, with hundreds of species of plants and animals disappearing from the planet on a daily basis.

Tundra Biomes : 

Tundra Biomes In the tundra, conditions are cold, with an annual average temperature less than 5 C, and precipitation (mostly in the form of snow) less than 100 mm per year (see figure at right).  The summer is brief, with temperatures above freezing lasting for only a few weeks at most.  However, this "warm" summer coincides with periods of almost 24 hour daylight, so plant growth can be explosive.

Taiga Biomes : 

Taiga Biomes “Taiga” is a Russian word meaning dense evergreen forest. The taiga biome, the largest biome on land, is full of dense evergreen forests. Located just south of the tundra in the northern parts of Europe, Asia, and North America, these forests of conifer trees are also known as boreal forests. It is very cold and snowy in the taiga during winter, with below freezing average temperatures. While it is not uncommon for temperatures to dive below freezing during the summer as well, it is generally warmer then. Days are long during summer in the taiga, ice thaws, snow melts, and it is often rainy.

Coral Reef : 

Coral Reef Coral reefs are aragonite structures produced by living organisms. In most reefs the predominant organisms are colonial cnidarians that secrete an exoskeleton of calcium carbonate. The accumulation of this skeletal material, broken and piled up by wave action and boarders, produces massive calcareous formations that make ideal habitats for living corals and a great variety of other animal and plant life.
