Question

On the basis of our discussion of food-chain energetics, explain how the global human population's need for food could be met more readily if meat consumption were reduced and people lived more on plant foods. Discuss hypotheses for why Burmese pythons deconstruct their digestive systems between meals. Similarly, discuss hypotheses for why small birds and mammals, having lengthened their intestines during cold seasons, permit their intestines to shorten during warm seasons. In other words, why might natural selection favor plastic, rather than static, gastrointestinal morphology? Most people tend to think that if the sun ever stopped emitting light, all animal life on Earth would soon end. Populations of hydrothermal-vent animals might continue to exist for thousands of years, however. Explain.

Explanation / Answer

According to the 10% law during the transfer of energy from organic food from one trophic level to the next, only ten percent of the energy from organic matter is stored as flesh. The remaining energy is lost during transfer by higher trophic level. So when meat is consumed the overall energy obtained from it is very less than obtained from plants because energy is lost during the transfer of energy. So if we consume less meat then the energy from the chain is less wasted. S if we consume more plant then the food need of population can be easily obtained.
