Concept of Eco-system

Generally, Eco-system is called the system of ecology. There is created different unit, organization or spatial on earth interrelation of biological community and their environment that process helps for moving biotic living cycle  continuous in ecology. The level of power and material flows from low to high level in environment. Eco-system refers the functional and structural unit of biological
community and their relationship with physical environment. Eco-system is known as the origin of ecological system from inter-dependent or interactions of biotic objects with environment. Required power and material transfer unit for biotic objects built from interaction or inter-dependent between living and nonliving things. So, nature of material flows one to another from built unit. Required power and material comes to biological environment from natural environment as a photosynthesis process. It works as nutrient for development, growth and expansion of bio-world.

Eco-system is a dynamic system where the living and nonliving components are constantly interacting and bringing structural and functional change of basic functional unit of organism. Structure and function both falls on organization condition of Eco-system. Determined of structural organization from continuously interaction between living and nonliving components and represent the composition of biotic community, amount components and distribution of abiotic and geographical situation. In that way, functional organization condition presents inner and outer interrelation or inter-dependent level of biotic units. Eco-system is one open system because it helps to identify biological diversity, functional organization unit of biology and geographical condition.
