Dung beetles and disease carrying flies both compete for the same food, that is cattle droppings. Since both of these organisms belong to different species, this competition is called interspecific competition.

The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Therefore out of various power resources government relies on thermal power.

The Nobel for Economic Sciences in 1998 was won by Kolkata-born economist Amartya Sen "for his contributions to welfare economics." India-born Venkatraman Ramakrishnan won the 2009 Nobel Prize along with two others in Chemistry "for studies of the structure and function of the ribosome." In 1998, Amartya Sen received the Nobel Prize “for his contributions to welfare economics.” Much of Sen's early work was on issues raised by kenneth arrow's “impossibility theorem.” Arrow had shown, much more generally than Condorcet had in 1785, that majority rules often lead to intransitivities.

A new online Atlas of freshwater biodiversity has been launched on 29 January, 2014. It will present spatial information and species distribution patterns. TheAtlasis an output of BioFresh – an EUfunded project in which the IUCN Global Species Programme is a key partner. It is working to better understand, manage and protect our freshwaters, for generations to come. 

Tree foundation, an NGO engaged in conservation of the sea turtle, found more than 100 dead Olive Ridley turtles in the shores of Nagapattinam. The Olive Ridley turtles are rusty coloured carapace and have slightly smaller head and shell than the Kemp turtles. These Olive Ridley turtles generally occur through the Antilles, around the north coast of South America, in West Africa, the Indian Ocean, Australia and Southeast Asia. As per the reports the populations of Olive Riddles have declined in Pakistan, Myanmar, Malaysia and Thailand, and possibly on the east coast of India, south of Orissa and in the Andaman and Nicobar islands.

A biodiversity hotspot is an area with an unusual concentration of species, many of which are endemic. It is marked by a serious threat to its biodiversity by humans. The concept was given in 1988 by Norman Myers. The British biologist Norman Myers coined the term "biodiversity hotspot" in 1988 as a biogeographic region characterized both by exceptional levels of plant endemism and by serious levels of habitat loss. In 1990 Myers added a further eight hotspots, including four Mediterranean-type ecosystems.

White-bellied Heron (Ardeainsignis), Great Indian Bustard (Ardeotisnigriceps) and Forest Owlet (Atheneblewitti) are some, among the list of endangered birds of India. Mallard (Anasplatyrhynchos) is a dabbling bird, which is not an endangered bird.
