Biotic Components of Ecosystem
Living beings in environment like animals and plants constitute more than half of the environment in the biosphere. All of these need to be conserved.

When both the ovaries are fully mature, they alternatively produce ova at the interval of 28 days. Release of ovum into the uterus through the fallopian tube is called as ovulation.
Growing a single crop species over a large area or farm is called intensive farming or monoculture. Earlier practices of mixed cropping caused problems in crop management, like harvesting, etc. Uniformity in plant height adds beauty to our fields and makes the application of agrochemicals easy. It also saves time and energy in segregating grains in threshing.
Sometimes it so happens that serious and abrupt changes in weather condition ruin the entire crop. Thus, the hard work of the whole season goes in vain. What about the debt which he has to pay? On the other hand, market prices of his agriculture production often remain too less to support the economy of the farmer. These are the conditions under which a number of farmers in different states of India have been reported committed suicides.
We may know that there are two types of disasters: Natural and Manmade or Human Induced Disasters. Disasters that occur…
Environment may be defined as ‘Complete range of various sets of external conditions comprising- physical, biological, and for human beings- cultural, economic and political conditions; in which human beings and other life forms exist in continuous interactions among themselves.
It is due to frequent oil spills that sea otters, many sea birds, whales and many other species of the marine environment have become endangered. The oil spill damages fisheries and Mari culture, and causes serious economic losses to the local public and the governments.
Medicinal weed Argemone Mexicana or Satyanasi is a prickly weed. It has been introduced and naturalized in India. It grows as waste land weed in almost every part of the country. It is reported as crop weed also in many parts of the country.
All biosphere ecosystems have well-organized functions, such as cycling nutrients through food chains, operating biogeochemical cycles, and maintaining the energy flow received by green plants through solar radiation.
The regular pattern of weather conditions of a particular place is called as climate of that place. This regular pattern of weather conditions is considerably disturbed by fluctuations in temperature. The disturbance in the pattern of weather conditions at the particular place may thus be called as Climate Change.
The Wind is Air in Motion. It is caused by differential heating of land, water, hills and mountain slopes by sun rays. About 25 % (i.e., 0.34 KW/m2) of incident solar radiation is dissipated as wind energy. There is kinetic energy in wind.
The concept of joint forest management was initiated on a large scale through guidelines issued by the government of India in 1990. According to those guidelines the village communities are to be involved in the development and protection of degraded forests based on taking their genuine share of benefits from those forests.
