Reil [10]

The leading cause of limited water supplies is low precipitation. Anything will not be limited until a huge production has been created. Hence, overuse, limiting use, and government are not responsible for the cause of limited water supply.

<h3>What do you mean by Precipitation?</h3>

Precipitation may be defined as any sort of water that originates in the Earth's atmosphere and then falls onto the surface of the Earth. It includes snow, rain, hail, dew, etc.

Precipitation is considered the major component of the water cycle that mediates the transport of water movement across the planet. If it declines, the supply of water gets limited.

Therefore, the leading cause of limited water supplies is low precipitation.

Ahat [919]

Following general conditions are necessary for natural selection to occur in population:

  • More organisms are born than can survive.
  • Organisms vary in their characteristics, even within a species.
  • Differences in reproduction and survival are due to variation among organisms.

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Galapagos Finches: The Galapagos finches studied by Darwin on his famous voyage are probably the most common example of natural selection.
