INTRODUCTION Energy flow in environment is the important function in the ecosystem. The storage of the energy in the ecosystem is based on two basic laws of thermodynamics. The first law of thermodynamics states that when energy is converted from one form into another, energy is neither created nor destroyed.…
INTRODUCTION Abiotic and biotic factors or components are present in environment of an organism. The abiotic factors includes the atmosphere(air), hydrosphere (water), and lithosphere( land including soil).The abiotic factors are characterized by physical and chemical factors such as light, temperature, rainfall, pressure, pH, the content of oxygen and other gases.…
INTRODUCTION Environment and biosphere: Every living organism has its own surrounding, medium of environment to which it interacts and is adapted to it. The environment is the sum total of physical or abiotic and biotic conditions influencing the organisms. The life supporting environment of planet earth is biosphere. The biosphere…
