PLEASE ANSWER QUICKLY Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem. All of the following must be addressed in your response to receive full credit:

a. Discuss the transfer of biomass when one organism eats another. Use your knowledge of digestion to discuss how food is broken down and used by the consumer.

b. Explain what happens to the energy that is not transferred from one organism to another.

c. Explain why there are typically fewer organisms at the top of an energy pyramid.

d. Use specific numbers and calculations to support your explanation.

a)      When a prey is eaten by a predator, the tissue that is ingested by the predator is broken down in the digestive system of the organism to smaller molecules that can be absorbed by the organisms. These molecules, lipids, amino acids and glucose are used by the predator to build its tissues and in the provision of energy.

b)      Because not all energy is used efficiently, some are lost because of the ingested food not being fully digested and absorbed, hence waste is passed as fecal matter. During the process of digestion and biological processes, a higher percentage of energy is also lost as heat in the process.  

c)       Due to this inefficiency in the transfer of energy from trophic level to another up the energy pyramid, which is lost as heat , there are fewer organisms up the trophic levels than below the trophic levels. Hence the characteristic shape of the energy pyramid.  

d)      Since only 10% of energy is passed from one trophic level to another in the form of biomass, then if we had 10,000 primary consumers in an ecosystem, the highest number of secondary consumers in that ecosystem would be 1,000.
