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.

The total area where living beings are found is called as biosphere. It can be divided into many small independent units called as Ecosystem. In fact, the unit of biosphere which incorporates many types of microorganisms, plants and animals, physical factors like soil, water, air etc. interacting among themselves is called as ecosystem
The biosphere is itself a vast ecosystem which incorporates all the small ecosystems. But, the biosphere may have different types of physical conditions, communities of plants and animals, and climatic conditions in its different zones.
Nearly half of the planet’s plant and animal species live in Rainforests. Less than 2.5 billion acres of Tropical Forest have remained out of four billion acres on the Earth within a few hundred years.
The conditions of a habitat remain changing abruptly and periodically. Abrupt changes in environment often do not give time to an organism to get ready and to face the challenges. As such the organism can survive only when it has sufficient abilities to tolerate these changes.
An activity that serves as one’s regular source of livelihood is called as occupation.

About 1000J radiant energy comes to the earth from the sun. Out of this, only 10% of the total energy is used up by green plants in the process of Photosynthesis. Remaining 990J of energy escapes away into the atmosphere. 10J of energy is stored in the form of chemical energy in starch and sugars.
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.
The scientists of Punjab Agricultural University (PAU), Ludhiana worked for ten years to develop a new High Yielding Variety of onion entitled POH-1.
Many people are working longer and harder, thinking that this will solve the problem of an ever-increasing workload. But they are still falling behind, becoming chronically overwhelmed, and burning out.
The Conservation Status of Biodiversity is usually known through the comprehensive Inventory prepared periodically by the IUCN, the International Union for the Conservation of Nature and Natural Resources. This comprehensive Inventory of the Conservation Status of Species is popularly known as the Red List or the Red Data List.
