Natural selection is a theory popularized by Charles Darwin. It's a key mechanism of evolution. When a gene or an aspect of an organisms dna isn't up to par with the environment, it starts to change over time. Over time this can result in various groups being much more adapted to a specific environment. It is considered the leading proof for adaptive evolution. An example would be, if there was a population of green bugs and red bugs. The birds in this area were more attracted to the red bugs than the green bugs. Natural selection may take place and the species would the red bugs would get cut out as generations went on and in time, there would be mostly or only green bugs.

Answer:

450 kilocalories.

Explanation:

Since only 1/10th of the energy that an organism consumes is passed onto the next level of the pyramid, that would mean only 500/10 = 50 kilocalories are passed on, and the remaining 500 - 50 = 450 kilocalories are used up.

Hope this helped!
