Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.

Answer:
genetics
Explanation:
calico cats must also inherit a gene unrelated to the X and Y chromosomes that codes for white fur. Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. About one in every 3,000 calico cats is born a male, and, unfortunately, don't live as long as female calicos due to their genetic abnormalities. XXY Syndrome renders male calicos sterile and can be the root cause of many other health problems

The reason for the loss of color after the industrial revolution is that the light-colored moths were "selected against" by predators. These birds could only see the light ones against the newly dark, sooted background. Over time, these predators could no longer distinguish the dark ones from their natural dark, sooted background. Thus more light-colored moths stood out against the dark soot, and were eaten. And more dark-colored moths eluded the birds, survived to reproduce, passing on more of their dominant genes for dark color to their offspring. After several decades of hundreds of thousands of generations, most of the later generations were dark, due to selective advantage of camouflage to survive predation.
