Question : 27 [SCC CGL 2008]
Which one of the following is an abiotic and renewable resource?

Answer »Answer: (c)
In ecology and biology, abiotic components (also known as abiotic factors) are non-living chemical and physical factors in the environment, which affect ecosystems. Abiotic phenomena underlie all of biology.
From the viewpoint of biology, abiotic factors can be classified as light or more generally radiation, temperature, water, the chemical surrounding composed of the terrestrial atmospheric gases, as well as soil.
The macroscopic climate often influences each of the above. A renewable resource is a natural resource with the ability to reproduce through biological or natural processes and replenished with the passage of time. Renewable resources are part of our natural environment and form our ecosystem.

The food chain refers to the transfer of energy from :
a) organisms of the land to those of the sea by means of river
b) lower to higher latitudes
c) one organism to another
d) the interior of the earth to the surface
Answer »Answer: (c)
A food chain is a linear sequence of links in a food web starting from a trophic species that eats no other species in the web and ends at a trophic species that is eaten by no other species in the web.
A food chain differs from a food web because the complex polyphagous network of feeding relations are aggregated into trophic species and the chain only follows linear monophagous pathways. A common metric used to quantify food web trophic structure is food chain length. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web and the mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.
Food chains were first introduced by the African-Arab scientist and philosopher Al-Jahiz in the 9th century and later popularized in a book published in 1927 by Charles Elton, which also introduced the food web concept.
