Environment and its ecology

The environment includes rock, soil, water, air, atmosphere, and living things. The relation between the components of the environment is called ecology. For the existence of life, ecology is a more important factor. The biosphere is the one where life exists and it occupies 0.00008 percent of the mass of the earth. This includes the lower part of the atmosphere, the hydrosphere, and the lithosphere. In the atmosphere, there is only a small percentage of life exist. The hydrosphere takes the largest portion among these three. The lithosphere is the upper region of soil and rocks. The atmosphere contains all gases that need for the life to exist. The major source of energy is the sun and the plants store that energy using the process called photosynthesis. 

Sunlight broke down into three major components namely visible light, ultraviolet, and infrared radiation. For photosynthesis the visible light range is important. The energy flows through the food chain in the environment. Producers in the environment are plants. primary consumers are herbivores. The predation starts from the next level in the food chain. 

Many cycles control and renew the sources such as the water cycle, nitrogen cycle, carbon cycle, etc. With the human impact, the balance of the environmental processes has been interrupted.
