3. Consider the energy pyramid. Which statement best summarizes what happens to energy as it flows through the food chain?
- The amount of energy transferred between trophic levels decreases up the food chain
- The amount of energy transferred between trophic levels increases up the food chain.
- The amount of energy transferred between any two trophic levels of a food chain is the same.
- The amount of energy at each trophic level of a food chain is independent of the other levels

Answer: B. sugar; respiration
Explanation: To obtain energy needed for life processes and activities, respiration must occur. Respiration involves the break down of glucose (A disaccharide sugar) to produce energy in form of ATP.
The equation for respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
The muscle fibres use several substrates in order to perform contractions. ATP is one of them. It binds to the myosin head and causes contraction. Creatine phosphate is another substrate that works in the "background" storing energy to convert ADP into ATP quickly as ATP is being used. Glycogen is another of the muscle fibres' substrates. It's used to produce energy quickly when creatine phosphate runs out of phosphates to use on ADP. The use of glycogen leads to the deposition of lactic acid on the muscles.
When these substrates run low there is muscle fatigue (or also called, in this case, metabolic fatigue) - there's no energy. Another cause may be from the deposition of lactic acid that also leads to such fatigue.
