Biosphere Dynamics

As long as it is known that the earth is the only place the presence of life. Every living thing occupies a suitable environment for life. They interact with the environment in it, including the atmosphere, lithosphere, hydrosphere. All the concepts of learning about the life of an organism that takes place in layers of earth and its interactions with the environment, including the biosphere. Biosphere studied to provide knowledge about the effects of changes in the biosphere of life on earth. In this chapter will also examine the adaptation of every living creature with its environment respectively, and changes in the biosphere that affects the damage to flora and fauna.

Distribution of Flora and Fauna

Distribution of flora and fauna on earth vary from one place to another place. For example dragons exist only on the islands of Komodo, Rinca, and Padar island in NTT. Distribution is closely related to the geographical conditions which also has a background history of geology. Distribution of flora and fauna not only in mainland but also in the waters of both freshwater and marine waters.

Alfred Russel Wallace (1823 - 1913)

Alfred Russel Wallace was an expert in evolution, nature, anthropology, and geography scientists. He is British, born in Gwent (Monmouthsire), England, on January 8, 1823. Alfred Russel Wallace was dubbed the "Father of Geography Animals. The nickname was acquired because he had made observations against the spread of the animals in the world and divide it in some dispersal areas. When he made the observation that there are animals in the territory of Indonesia, he mereasa impressed because he found no differences between animals in the western part of Indonesia with the animal in Indonesia bagia east. Limits difference begins from Lombok Strait to Strait of Makassar. Therefore, the boundary line is called line of Wallacea (Wallacea's line) in accordance with the name of the inventor "Alfred Russel Wallace."

Biosphere can be regarded as the greatest life organization includes all life on this earth and its interaction with the environment. Every living creature on this earth occupy their respective places of his life both on land (lithosphere), water (hydrosphere), and air (atmosphere). If the pull straight line, about 8 km to the angry atmosphere and 9 km to the ocean floor. Because based on research data on height or into it still found the existence of life. Etymologically the term biosphere is a combination of two words, namely bio which means life and sphera which means layers. Thus it can be justified if the biosphere is said as a layer (area) occupied by living things are animals, plants and humans, but humans will not have much discussed at this layer because the human being has its own specificity as social beings. humans inhabit their own environment called antroposfer. It is estimated that the biosphere has been going on for 4.5 billion years old.

Habitat.

A suitable environment and suitable for the survival of non-human beings (flora and fauna) is called as a habitat. Habitat can affect every living thing in it and interact with different ways. Like the existing plant in the savanna regions can become food for a group of herbivorous animals. Type of plant and spreading in a number of habitats affects the amount and type of animals that can live in these habitats. Conversely any plant can be affected by the presence of animals. For example, as shown in the above types of flowering plants require insects to carry pollen from one flower to another.

Habitat can be divided into two kinds of habitat land and water habitats. Terrestrial habitats can be studied in a system called bioma while water habitat is divided into habitat for freshwater and saltwater (marine). 70% of the Earth's surface is covered by sea water, the sea can be regarded as the largest habitat on earth.
