Eco Environment

In the earth, there are numerous plants, animals, and organisms. The living beings are dependable to each other and interrelated. They differ with each other in terms of their habitat, life cycle, reproduction etc. The living beings are classified into various categories for the convenience of study. There is a diversity and difference in living beings which are found on the surface of the earth. The biodiversity includes the varieties of existing living beings in per unit area of earth. The types and diversity of different living beings denote the biodiversity. Biodiversity also includes the variation in ecosystem, where organism and gene play an important role. The ecosystem of different places differs due to biodiversity. The ecosystems are habitats that are suitable to different types of organisms and species. Biodiversity is different with the nature of ecosystems. Biodiversity of a location refers to the existence of organisms and species of living beings per square unit. Biodiversity indicates the total of the living heritage of the earth and their status as well as their differences. It also indicates the system and structure of the living beings in the nature. Greek Philosopher Aristotle has identified 500-600 species of animals and plants. Biodiversity can be classified into species, genes and ecosystem. There are various types of ecosystems. Animal and plants have peculiar kind of adaptation. Ecosystem is the habitat of living beings. Living beings adjust in the ecosystem and survive there. Each organism has its own heredity character, which helps them to adapt and survive in their habitat.
The characteristics of the ecological belts of any country determine the kind of biodiversity. Therefore, there is diversity in living beings according to place. Some organism is found in land, some in water and some in atmosphere. There is some vegetation which grows on watersheds and surface of water too. There is a close relationship among the various types of living beings. If their relationship is broken it causes them difficulty to live in. but destruction of any one of the species harms to ecological balance. For instance, the life cycle of vegetation, birds and animals and other living beings is adversely affected due to the destruction of forest. It becomes very difficult to survive under deteriorating situation of ecosystem. Genetic diversity can be measured within a variety of DNA and other techniques. New genetic variation is produced in populations of organisms that can reproduce sexually by recombination and in individuals by gene and chromosome mutations. In each ecosystem, living creatures form a community, interacting with one another and with air, water and soil around them.
